// This code is useful for popup pictures (e.g. thumbnails //
// you want to show larger, such as a larger version of a //
// product photo for example) but you don't know the image //
// dimensions before popping up. This script displays the //
// image with no window border, and resizes the window to //
// the size it needs to be (usually better to spawn it //
// large (600x400 for example) and let it auto-resize it //
// smaller), and if the image is larger than 90% of the //
// current screen area the window respawns itself with //
// scrollbars. //
// //
// Usage: //
// window.open('showpic.php?src=big.jpg&title=Big+picture', //
// 'popupwindowname', //
// 'width=600,height=400,menubar=no,toolbar=no') //

//////////////////////////////////////////////////////////////
The phpThumb() distribution includes several demos, and it
should be self-evident what they do when you run them:
* phpThumb.demo.demo.php - shows a wide variety of samples,
basically all the different features and filters of phpThumb.
Note: sample image files are not included in the distribution
but can be downloaded from http://phpthumb.sourceforge.net/demo
* phpThumb.demo.check.php - configuration checker, will check
your config file and server configuration and warn of any
potential problems
* phpThumb.demo.object.php - example of how to call phpThumb
as an object.
* phpThumb.demo.random.php - select & display a random thumbnail
from a directory of images.
* phpThumb.demo.showpic.php - auto-resizes a popup window to
match the dimensions of the image it is displaying
Other people have created useful demos and/or extensions to
phpThumb(). Some of these I know of are:
* iManager - http://www.j-cons.com/news/
* iBrowser - http://www.j-cons.com/news/
* ThumbnailSelector - http://www.silisoftware.com/scripts/ThumbnailSelector
If you know of any others you think should be mentioned here

// Frequently Asked Questions (FAQ) about phpThumb() //
// ///
//////////////////////////////////////////////////////////////
Q: My question isn't answered here and I can't find any
forums, how do I get support?
A: Please email me directly at info@silisoftware.com with
any questions, suggestions, donations, etc.
Q: What is the GPL? Can I use this for commercial sites?
A: See the GPL FAQ: http://www.gnu.org/licenses/gpl-faq.html
In general, if you just want to call phpThumb.php in the
standard <img src="phpThumb.php?src=pic.jpg&w=100"> manner
then there is no problem, you're free to do this no matter
if you site is commercial or not, or what license your code
is released under.
If you're calling phpThumb() as an object then you will
probably run into license issues, so consult the above FAQ
and the GPL itself.
No matter if you use phpThumb() commercially or not, no
payment is required. However, donations are always welcome
and can be made at http://phpthumb.sourceforge.net
Q: Some images generate thumbnails, but some fail (the original
non-resized image is output instead).
A: Your PHP installation does not have a high enough memory_limit
and ImageMagick is not installed on the server. The PHP memory
required is 5 times the number of pixels in the image.
For example:
640x480x5 = 1.5MB
1600x1200x5 = 9.2MB
You can adjust the PHP memory limit in php.ini (if you have
permission on your server to do so), or (better yet) install
ImageMagick on the server and that will bypass the memory limit
issue. If you can't do either of the above, you can resize the
images manually (with your favourite image editor) to a size
that your memory_limit setting can handle, and/or you can
re-save the images with an image editor that can embed an EXIF
thumbnail (Photoshop for example) which phpThumb can use as an
image source (lower image quality, but perhaps better than
nothing).
Q: I'm getting is this error message:
Failed: RenderToFile(<filename>) failed because
!is_resource($this->gdimg_output)
A: You missed the call to GenerateThumbnail() before
RenderToFile() or OutputThumbnail.
See /demo/phpThumb.demo.object.php for an example.
Q: I'm trying to save a phpThumb-generated image in Internet
Explorer and it saves in BMP format, why?
A: This is not phpThumb's fault, it is an IE issue:
http://support.microsoft.com/default.aspx?scid=kb;en-us;810978
http://support.microsoft.com/default.aspx?scid=kb;en-us;260650
Q: PNG images with transparent areas show up with gray background
in the areas that are supposed to be transparent.
A: Internet Explorer has had a broken PNG alpha-channel display
implementation for a decade, so it may never get fixed. Other
major browsers generally handle alpha-transparent PNGs fine.
See http://www.silisoftware.com/png_transparency/
For an alpha-channel PNG display in IE hack, see this page:
http://www.koivi.com/ie-png-transparency/
Q: I'm getting "<filename> does not exist" when I know the
file does exist
A: Check these two values are present and properly configured
in phpThumb.config.php (introduced in v1.6.0):
$PHPTHUMB_CONFIG['allow_src_above_docroot'] (default=false)
$PHPTHUMB_CONFIG['allow_src_above_phpthumb'] (default=true)
If your images are outside DOCUMENT_ROOT then you will have
to configure 'allow_src_above_docroot' to true.
Q: Should I use phpThumb.php, or use phpThumb() as an object?
A: phpThumb.php is easier to use (less coding) for basic uses.
phpThumb.php handles all caching; your own object will need
to have its own caching code. If you just want to display a
thumbnailed version of an existing image, use phpThumb.php
If you want to render one (or more) thumbnails to static
files (during upload, for example), that's an appropriate
use for the object mode. Also, phpThumb.config.php is only
used by phpThumb.php, so if you instantiate your own object
you need to manually set all configuration options because
phpThumb.config.php has NO effect. So, to repeat:
**always use phpThumb.php unless you NEED to have an object**
Q: Are there any front-end GUI interfaces to phpThumb()?
A: See /demo/readme.demo.txt
Q: Are there / have there been any security issues in phpThumb?
A: http://secunia.com/product/5199/
Q: Why can't Flash work with images output from phpThumb()?
A: Flash doesn't like progressive JPEG. Set:
$PHPTHUMB_CONFIG['output_interlace'] = false;
Q: Image quality is not very good - why?
A: If you're using GD v1.x, no way around it. Upgrade to GD v2.x
Q: Image quality is very bad, very pixelated -- why?
A: You may be trying to resize images larger than the available
PHP memory, so phpThumb is simply extracting and using the
EXIF thumbnail as the image source, which is usually about
160x120 (so if you resize it to 640x480 it will look very bad).
To calculate the required size for memory_limit in php.ini,
calculate the number of pixels in the image and multiply by 5:
For example, 1600x1200 = 1600 * 1200 * 5 = 9600000 = 10M
Q: Can I save the generated thumbnail to a file?
A: Yes, there are several ways to do so; the best way is to call
phpThumb as an object and call RenderToFile() to save the
thumbnail to whatever filename you want.
See /demo/phpThumb.demo.object.php for an example.
The other way is to use the 'file' parameter (see
/docs/phpthumb.readme.txt) but this parameter is deprecated
and may not exist in future versions of phpThumb().
Q: "Off-server thumbnailing is not allowed" -- how do I enable it?
A: By default, phpThumb() only makes thumbnails for the same domain
that it is running on. To allow it to make thumbnails for a limited
number of other domains, add them (in phpThumb.config.php) like this:
$PHPTHUMB_CONFIG['nohotlink_valid_domains'] = array(
@$_SERVER['HTTP_HOST'], 'example.com', 'www.example.com',
'subdomain.example.net', 'example.org');
To disable off-server thumbnail blocking, just set:
$PHPTHUMB_CONFIG['nohotlink_enabled'] = false;
Q: Is it possible to set the parameters (like w/h/fltr[]) in the config,
so that they can't be changed over the URL?
A: Take a look at $PHPTHUMB_DEFAULTS at the bottom of phpThumb.config.php
You'll want to set $PHPTHUMB_DEFAULTS_GETSTRINGOVERRIDE=false,
possibly also $PHPTHUMB_DEFAULTS_DISABLEGETPARAMS=true.
You may also want to investigate $PHPTHUMB_CONFIG['high_security_enabled']
(see the example at the bottom of phpThumb.config.php for how to call
images in HighSecurity mode.
Q: Is there a way to use phpThumb() object to create thumbnails without the
parameters in the URL showing the location of the image etc?
A: There is a demo in /demo/phpThumb.demo.object.php. You could modify this
into your own file, but there still remains the problem of passing
parameters to the file, whether it's phpThumb.php or your own instantiation
of a phpThumb() object. I would suggest is putting as many of the common
parameters into phpThumb.config.php as possible under $PHPTHUMB_DEFAULTS,
so you then don't have to pass them for each image. If you don't want people
modifying the parameters, turn on $PHPTHUMB_CONFIG['high_security_enabled']
and set a password (you'll need to generate the <img> tags with phpThumbURL()
provided at the bottom of phpThumb.config.php). If you don't want people
accessing your source images at all, you can place them outside DOCUMENT_ROOT
on your server (as long as phpThumb/PHP has read access to the directory).
The other option is to put your source images in a MySQL database and set
$PHPTHUMB_CONFIG['mysql_query'] and related parameters in phpThumb.config.php
to pull your source images from the database. That way it's impossible to
retrieve the images except through phpThumb.php, and if high_security is enabled,
then nobody can modify the parameters to view anything except what you want to show.
So, yes, it's possible to use your own object, but it's probably better to use
phpThumb.php if possible -- one notable issue is that phpThumb.php handles all
the caching, so you're on your own to deal with that if you create your own object.
Q: phpThumb runs slowly, as if the images aren't cached, when I use HTTP source
images (not on my server). How can I make it go faster?
A: $PHPTHUMB_CONFIG['cache_source_filemtime_ignore_remote'] = true;
// if true, remote source images will not be checked for modification date and
// cached image will be used if available, even if source image is changed or removed
Q: What does the "cache_default_only_suffix" configuration option do?
A: Cache files are normally created with big ugly names like
"phpThumb_cache_www.example.com_src1a482c2c760463795ff18faf073b389f_par3e099041c2f4a73041a7f5d7e7fc481a_dat1119952152.jpeg"
but if cache_default_only_suffix is enabled, cache filenames are simplified to
"pic_thumb.jpg" (for example). The problem is that only one version of that
thumbnail is possible, and you can never call it again with a different size,
or different filters, etc. Generally you don't want that enabled, but it's
there because some people asked for it.
Q: Why is the visual size of rotated images smaller than the unrotated images?
A: phpThumb fits the rotated image into the 'w' and 'h' dimensions.
Try not specifying a 'w' parameter: phpThumb.php?src=file.png&ra=15
That should leave the image the apparent same size as the unrotated image
(in actual fact the canvas size is enlarged to fit the rotated image in it).

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

============
Description:
============
phpThumb() uses the GD library to create thumbnails from
images (GIF, PNG or JPEG) on the fly. The output size is
configurable (can be larger or smaller than the source),
and the source may be the entire image or only a portion
of the original image. True color and resampling is used
if GD v2.0+ is available, otherwise low-color and simple
resizing is used. Source image can be a physical file on
the server or can be retrieved from a database. GIFs are
supported on all versions of GD even if GD does not have
native GIF support thanks to the GIFutil class by Fabien
Ezber. AntiHotlinking feature prevents other people from
using your server to resize their thumbnails, or link to
your images from another server. The cache feature
reduces server load.
======
Usage:
======
Call phpThumb() just like you would a normal image.
Examples:
<IMG SRC="phpThumb.php?src=/image.jpg&w=100">
<IMG SRC="phpThumb.php?src=http://example.com/foo.jpg">
See the "demo" link on http://phpthumb.sourceforge.net
for more usage examples). Parameters that can be passed
are listed below under "URL Parameters".
NOTE: It's recommended you use the local image filename
wherever possible (rather than http://) because performance
is much better, less (or no) use of temp files, and the
last-modified check for cached files doesn't work for
remote files.
To access files over a LAN with Windows share names you
must use the network name (or IP) and not a mapped drive
name, for example:
//othercomputer/file.jpg - good
//192.168.2.1/file.jpg - good
z:/file.jpg - won't work
This is a PHP limitation (see www.php.net/file-exists)
Note: you may want to use "/" slashes instead of "\" if
you have magic_quotes_gpc enabled to avoid stripslashes
problems, although either slash should work if
magic_quotes_gpc is disabled
================================
Alternate PATH_INFO-style Usage:
================================
phpThumb.php can also be called by passing parameters not
after the usual "?" but like this:
phpThumb.php/<params>=<values>;<w>x<h>;<image>
For example:
phpThumb.php/100;pic.jpg
phpThumb.php/100;images/pic.jpg
phpThumb.php/100;/images/pic.jpg
phpThumb.php/100x200;pic.jpg
phpThumb.php/x200;pic.jpg
phpThumb.php/f=jpeg;q=50;100x200;pic.jpg
phpThumb.php/fltr[]=usm;100;pic.jpg
<image> must be the last item. Dimensions must be the second-
last item. As many key/value pairs for parameters can be
passed before those last two items, with each pair joined by
equals ("=") and seperated by semicolon (";")
==============
Configuration:
==============
There are some configuration options you may (but are
not required to) change. Most configuration options can
be set when you call phpThumb() - see list below), but
default configuration options (such as cache directory)
are in phpThumb.config.php - this is the only file you
should ever modify.
The configuration file is distributed as
phpThumb.config.php.default to prevent accidental
overwriting of old configuration settings. Please
migrate your old settings to the new file (if upgrading),
or delete your old config and rename the default to
phpThumb.config.php
The amount of memory required for phpThumb depends on
several factors: the dimensions of the source image,
the dimensions of the output image, whether unsharp
masking is applied, whether watermarks are applied, etc.
The auto-detection of memory limits works as a general
"safe" value. You may be able to exceed the auto value
by a small or large amount, depending on whether you
apply watermarks and/or sharpening, and the output size
of your thumbnails. I do not currently have a reliable
formula for calculating such things, but I will attempt
to craft one for future versions of phpThumb(). Until
then, set "max_source_pixels" in phpThumb.config.php to a
value that works well for you (or leave it alone if the
defaults give you no problems).
The configuration options you should maybe modify are:
* cache_directory - thumbnailing is slow and processor-
intensive. Enabling caching will dramatically speed
up future thumbnail serving
* max_source_pixels - This should be auto-detected, but
if auto-detection fails and you get an invalid image
from large source images, set this to about 20% of
your available PHP memory limit.
* imagemagick_path - If the source image is larger than
max_source_pixels allows, but ImageMagick is available
phpThumb() will use it to generate the thumbnail.
///////////////////////////////////////////////////////////
Note: High-Security mode is recommended enabled if possible.
Set $PHPTHUMB_CONFIG['high_security_enabled'] in
phpThumb.config.php to enable it. Each call to phpThumb
needs to be made through the function supplied at the
bottom of phpThumb.config.php which create the hash:
require_once('phpThumb.config.php');
echo '<img src="'.phpThumbURL('src=pic.jpg&w=50').'">';
///////////////////////////////////////////////////////////
==============================================
Calling as an object (not using phpThumb.php):
==============================================
NOTE: most people don't need to and should not do this.
If you just want to display resized images, please just
use phpThumb.php, not the object mode. To render output
to one (or more) files instead of the browser, you should
skip phpThumb.php and instantiate your own object. Please
take a look at /demo/phpThumb.demo.object.php for details.
Note: phpThumb.php is where the caching code is located, if
you instantiate your own phpThumb() object that code is
bypassed and it's up to you to handle the reading and
writing of cached files.
===============
URL Parameters:
===============
src = filename of source image
new = create new image, not thumbnail of existing image.
Requires "w" and "h" parameters set.
[ex: &new=FF0000|75] - red background, 75% opacity
Set to hex color string of background. Opacity is
optional (defaults to 100% opaque).
w = max width of output thumbnail in pixels
h = max height of output thumbnail in pixels
wp = max width for portrait images
hp = max height for portrait images
wl = max width for landscape images
hl = max height for landscape images
ws = max width for square images
hs = max height for square images
f = output image format ("jpeg", "png", or "gif")
q = JPEG compression (1=worst, 95=best, 75=default)
sx = left side of source rectangle (default = 0)
(values 0 < sx < 1 represent percentage)
sy = top side of source rectangle (default = 0)
(values 0 < sy < 1 represent percentage)
sw = width of source rectangle (default = fullwidth)
(values 0 < sw < 1 represent percentage)
sh = height of source rectangle (default = fullheight)
(values 0 < sh < 1 represent percentage)
zc = zoom-crop. Will auto-crop off the larger dimension
so that the image will fill the smaller dimension
(requires both "w" and "h"). Set "zc=1" to enable.
(overrides both "iar" and "far")
bg = background hex color (default = FFFFFF)
bc = border hex color (default = 000000)
fltr = filter system. Call as an array as follows:
- "brit" (Brightness) [ex: &fltr[]=brit|<value>]
where <value> is the amount +/- to adjust brightness
(range -255 to 255)
Availble in PHP5 with bundled GD only.
- "cont" (Constrast) [ex: &fltr[]=cont|<value>]
where <value> is the amount +/- to adjust contrast
(range -255 to 255)
Availble in PHP5 with bundled GD only.
- "gam" (Gamma Correction) [ex: &fltr[]=gam|<value>]
where <value> can be a number >0 to 10+ (default 1.0)
Must be >0 (zero gives no effect). There is no max,
although beyond 10 is pretty useless. Negative
numbers actually do something, maybe not quite the
desired effect, but interesting nonetheless.
- "sat" (SATuration) [ex: &fltr[]=sat|<value>]
where <value> is a number between zero (no change)
and -100 (complete desaturation = grayscale), or it
can be any positive number for increased saturation.
- "ds" (DeSaturate) [ex: &fltr[]=ds|<value>]
is an alias for "sat" except values are inverted
(positive values remove color, negative values boost
saturation)
- "gray" (Grayscale) [ex: &fltr[]=gray]
remove all color from image, make it grayscale
- "th" (Threshold) [ex: &fltr[]=th|<value>]
makes image greyscale, then sets all pixels brighter
than <value> (range 0-255) to white, and all pixels
darker than <value> to black
- "rcd" (Reduce Color Depth) [ex: &fltr[]=rcd|<c>|<d>]
where <c> is the number of colors (2-256) you want
in the output image, and <d> is "1" for dithering
(deault) or "0" for no dithering
- "clr" (Colorize) [ex: &fltr[]=clr|<value>|<color>]
where <value> is a number between 0 and 100 for the
amount of colorization, and <color> is the hex color
to colorize to.
- "sep" (Sepia) [ex: &fltr[]=sep|<value>|<color>]
where <value> is a number between 0 and 100 for the
amount of colorization (default=50), and <color> is
the hex color to colorize to (default=A28065).
Note: this behaves differently when applied by
ImageMagick, in which case 80 is default, and lower
values give brighter/yellower images and higher
values give darker/bluer images
- "usm" (UnSharpMask) [ex: &fltr[]=usm|<a>|<r>|<t>]
where <a> is the amount (default = 80), <r> is the
radius (default = 0.5), <t> is the threshold
(default = 3).
- "blur" (Blur) [ex: &fltr[]=blur|<radius>]
where (0 < <radius> < 25) (default = 1)
- "gblr" (Gaussian Blur) [ex: &fltr[]=gblr]
Availble in PHP5 with bundled GD only.
- "sblr" (Selective Blur) [ex: &fltr[]=gblr]
Availble in PHP5 with bundled GD only.
- "smth" (Smooth) [ex: &fltr[]=smth|<value>]
where <value> is the weighting value for the matrix
(range -10 to 10, default 6)
Availble in PHP5 with bundled GD only.
- "lvl" (Levels) [ex: &fltr[]=lvl|<channel>|<min>|<max>
where <channel> can be one of 'r', 'g', 'b', 'a' (for
Red, Green, Blue, Alpha respectively), or '*' for all
channels based on average grayscale value (default).
<min> and <max> are the clip points for the levels
and are set to clip 0.1% of each end by default.
(range = 0-255) and are set to clip 0.1% of each end
by default. Use -1 for min and/or max to invoke auto-
detect mode. Using default parameters (&fltr[]=lvl)
is similar to Auto Contrast in Adobe Photoshop.
- "wb" (White Balance) [ex: &fltr[]=wb|<c>]
where <c> is the target hex color to white balance
on, this color is what "should be" white, or light
gray. The filter attempts to maintain brightness so
any gray color can theoretically be used. If <c> is
omitted the filter guesses based on brightest pixels
in each of RGB
- "hist" (Histogram)
[ex: &fltr[]=hist|<b>|<c>|<w>|<h>|<a>|<o>|<m>]
Where <b> is the color band(s) to display, from back
to front (one or more of "rgba*" for Red Green Blue
Alpha and Grayscale respectively);
<c> is a semicolon-seperated list of hex colors to
use for each graph band (defaults to FF0000, 00FF00,
0000FF, 999999, FFFFFF respectively);
<w> and <h> are the width and height of the overlaid
histogram in pixels, or if <= 1 then percentage of
source image width/height;
<a> is the alignment (same as for "wmi" and "wmt");
<o> is opacity from 0 (transparent) to 100 (opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
<m> is the edge (and inter-tile) margin in percent
- "over" (OVERlay/underlay image) overlays an image on
the thumbnail, or overlays the thumbnail on another
image (to create a picture frame for example)
[ex: &fltr[]=over|<i>|<u>|<m>|<o>]
where <i> is the image filename; <u> is "0" (default)
for overlay the image on top of the thumbnail or "1"
for overlay the thumbnail on top of the image; <m> is
the margin - can be absolute pixels, or if < 1 is a
percentage of the thumbnail size [must be < 0.5]
(default is 0 for overlay and 10% for underlay);
<o> is opacity (0 = transparent, 100 = opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
(thanks raynerape<70>gmail*com, shabazz3<7A>msu*edu)
- "wmi" (WaterMarkImage)
[ex: &fltr[]=wmi|<f>|<a>|<o>|<m>] where
<f> is the filename of the image to overlay;
<a> is the alignment (one of BR, BL, TR, TL, C,
R, L, T, B, *) where B=bottom, T=top, L=left,
R=right, C=centre, *=tile);
<o> is opacity from 0 (transparent) to 100 (opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
<m> is the edge (and inter-tile) margin in percent
- "wmt" (WaterMarkText)
[ex: &fltr[]=wmt|<t>|<s>|<a>|<c>|<f>|<o>|<m>|<n>|<b>|<O>|<x>]
where:
<t> is the text to use as a watermark;
Any instance of metacharacters will be replaced
with their calculated value. Currently supported:
^Fb = source image filesize in bytes
^Fk = source image filesize in kilobytes
^Fm = source image filesize in megabytes
^X = source image width in pixels
^Y = source image height in pixels
^x = thumbnail width in pixels
^y = thumbnail height in pixels
^^ = the character ^
<s> is the font size (1-5 for built-in font, or point
size for TrueType fonts);
<a> is the alignment (one of BR, BL, TR, TL, C, R, L,
T, B, * where B=bottom, T=top, L=left, R=right,
C=centre, *=tile);
<c> is the hex color of the text;
<f> is the filename of the TTF file (optional, if
omitted a built-in font will be used);
<o> is opacity from 0 (transparent) to 100 (opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
<m> is the edge (and inter-tile) margin in percent;
<n> is the angle
<b> is the hex color of the background;
<O> is background opacity from 0 (transparent) to
100 (opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
<x> is the direction(s) in which the background is
extended (either 'x' or 'y' (or both, but both
will obscure entire image))
Note: works with TTF fonts only, not built-in
(thanks mail<69>mmjaeger*com, craig<69>pc-fanatics*com)
- "flip" [ex: &fltr[]=flip|x or &fltr[]=flip|y]
flip image on X or Y axis
- "ric" [ex: &fltr[]=ric|<x>|<y>]
rounds off the corners of the image (to transparent
for PNG output), where <x> is the horizontal radius
of the curve and <y> is the vertical radius
- "elip" [ex: &fltr[]=elip]
similar to rounded corners but more extreme
- "mask" [ex: &fltr[]=mask|filename.png]
greyscale values of mask are applied as the alpha
channel to the main image. White is opaque, black
is transparent.
- "bvl" (BeVeL) [ex: &fltr[]=bvl|<w>|<c1>|<c2>]
where <w> is the bevel width, <c1> is the hex color
for the top and left shading, <c2> is the hex color
for the bottom and right shading
- "bord" (BORDer) [ex: &fltr[]=bord|<w>|<rx>|<ry>|<c>
where <w> is the width in pixels, <rx> and <ry> are
horizontal and vertical radii for rounded corners,
and <c> is the hex color of the border
- "fram" (FRAMe) draws a frame, similar to "bord" but
more configurable
[ex: &fltr[]=fram|<w1>|<w2>|<c1>|<c2>|<c3>]
where <w1> is the width of the main border, <w2> is
the width of each side of the bevel part, <c1> is the
hex color of the main border, <c2> is the highlight
bevel color, <c3> is the shadow bevel color
- "drop" (DROP shadow)
[ex: &fltr[]=drop|<d>|<w>|<clr>|<a>]
where <d> is distance from image to shadow, <w> is
width of shadow fade (not yet implemented), <clr> is
the hex color of the shadow, and <a> is the angle of
the shadow (default=225)
file = if set then thumbnail will be rendered to this
filename, not output and not cached.
(Deprecated. Disabled by default since v1.6.0.
You should instantiate your own object instead)
goto = URL to redirect to after rendering image to file
* Must begin with "http://"
* Requires file parameter set
(Deprecated. Disabled by default since v1.6.0.
You should instantiate your own object instead)
err = custom error image filename instead of showing
error messages (for use on production sites)
md5s = MD5 hash of the source image -- if this parameter is
passed with the hash of the source image then the
source image is not checked for existance or
modification and the cached file is used (if
available). If 'md5s' is passed an empty string then
phpThumb.php dies and outputs the correct MD5 hash
value. This parameter is the single-file equivalent
of 'cache_source_filemtime_ignore_*' configuration
paramters
xto = EXIF Thumbnail Only - set to only extract EXIF
thumbnail and not do any additional processing
ra = Rotate by Angle: angle of rotation in degrees
positive = counterclockwise, negative = clockwise
ar = Auto Rotate: set to "x" to use EXIF orientation
stored by camera. Can also be set to "l" or "L"
for landscape, or "p" or "P" for portrait. "l"
and "P" rotate the image clockwise, "L" and "p"
rotate the image counter-clockwise.
aoe = Output Allow Enlarging - override the setting for
$CONFIG['output_allow_enlarging'] (1=on, 0=off)
("far" and "iar" both override this and allow output
larger than input)
iar = Ignore Aspect Ratio - disable proportional resizing
and stretch image to fit "h" & "w" (which must both
be set). (1=on, 0=off) (overrides "far")
far = Force Aspect Ratio - image will be created at size
specified by "w" and "h" (which must both be set).
Alignment: L=left,R=right,T=top,B=bottom,C=center
BL,BR,TL,TR use the appropriate direction if the
image is landscape or portrait.
maxb = MAXimum Byte size - output quality is auto-set to
fit thumbnail into "maxb" bytes (compression
quality is adjusted for JPEG, bit depth is adjusted
for PNG and GIF)
down = filename to save image to. If this is set the
browser will prompt to save to this filename rather
than display the image
==============
General Notes:
==============
* Always use the local image filename wherever possible
rather than a full http:// URL because performance is
much better, less (or no) use of temp files, and the
last-modified check for cached files doesn't work for
remote files. For example:
good: phpThumb.php?src=/images/nicepic.jpg
bad: phpThumb.php?src=/home/httpd/example/images/nicepic.jpg
worse: phpThumb.php?src=http://example.com/images/nicepic.jpg
* Thumbnails will be scaled proportionately to fit in a
box of at most (width * height) pixels
(unless "iar" is set)
* Thumbnail caching for URL or database sources requires
an absolute directory name for $config_cache_directory
Physical file cached thumbnails will be recreated if
the source file changes, but remote/database files
cannot (modification time isn't readily available)
* If you need a GUI interface to phpThumb(), or for a user
to specify crop settings, or something like that please
see the list of known programs in /demo/readme.demos.txt
* Cropping images can be specified with either exact pixel
values for sx/sy/sw/sh parameters, or if those are set
to a value >0 and <1 then these are interpreted as a
percentage of the source image width/height. For example,
to crop 25% off all sides, you would specify parameters:
phpThumb.php?src=pic.jpg&sx=.25&sy=.25&sw=.5&sh=.5
* phpThumb() may have tempfile access issues on servers
where Safe Mode is enabled, specificly when accessing
a file over HTTP, or when a non-bundled version of GD
is in use. Specifying "config_temp_directory" may help
* Properly resolving /~user/ style filenames requires
apache_lookup_uri(), which is missing or broken in
Apache2, or if PHP is not installed as an Apache module.
phpThumb() does try and work around this if it is
unavailble, but you may have to specify a full filename
for "src" if you encounter problems.
* phpThumb() should work with PHP v4.0.6+, but seems to
have a few quirks before v4.1.0
EXIF thumbnail extraction requires PHP v4.2.0+
Image rotation requires PHP v4.3.0+. There have been
reports of problems with PHP older than v4.3.3
Some image filters require PHP v5.0.0+
Run /demo/phpThumb.demo.check.php to examine your server
* phpThumb() works better and faster when ImageMagick is
available. Most functions will work with only GD2, but
speed is much faster with ImageMagick, and much larger
images can be processed with ImageMagick than GD.
* phpThumb() works with GD v1.x, but works better with
GD v2.0+ because of the true-color image support
and ImageCopyResampled(). Also, there appears to be a
bug in ImageCopyResized() which is used with GD v1.x
where the bottom and/or right line of pixels is set
to the background color (due to a rounding error?)
NOTE: Please use the bundled version of GD if at all
possible (with PHP v4.3.0+) because the non-bundled
version has bugs which may cause PHP to crash:
* http://bugs.php.net/bug.php?id=21518
* http://bugs.php.net/bug.php?id=24174
phpThumb() has a workaround for the above bug but
there may be other bugs, and the workaround is slow.
Alpha transparent output requires GD >= 2.0.1 and
PHP >= 4.3.2
Most (if not all) filters require GD v2.x to function
at all. But many filters can be handled by ImageMagick
instead of GD.
* Filters handled by ImageMagick or GD:
- brit;cont;ds;sat;gray;clr;sep;gam;neg;th;rcd;flip;edge;
emb;lvl;blur;gblr;usm;
* Filters handled only by ImageMagick:
- none yet
* Filters handled only by GD + PHP5:
- sblr;mean;smth;
* Filters handled only by GD2:
- bvl;wmi;wmt;over;wb;hist;fram;drop;mask;elip;ric;bord;

/*
WARNING! Due to a known bug in PHP 4.3.2 this script is not working well in this version.
The sharpened images get too dark. The bug is fixed in version 4.3.3.
Unsharp masking is a traditional darkroom technique that has proven very suitable for
digital imaging. The principle of unsharp masking is to create a blurred copy of the image
and compare it to the underlying original. The difference in colour values
between the two images is greatest for the pixels near sharp edges. When this
difference is subtracted from the original image, the edges will be
accentuated.
The Amount parameter simply says how much of the effect you want. 100 is 'normal'.
Radius is the radius of the blurring circle of the mask. 'Threshold' is the least
difference in colour values that is allowed between the original and the mask. In practice
this means that low-contrast areas of the picture are left unrendered whereas edges
are treated normally. This is good for pictures of e.g. skin or blue skies.
Any suggenstions for improvement of the algorithm, expecially regarding the speed
and the roundoff errors in the Gaussian blur process, are welcome.
