// //
|
|
// 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') //
|
|
// //
|
|
// See demo linked from http://phpthumb.sourceforge.net ///
