* --
* This script provides a simple gallery of all images that are located
* in the script's directory and subdirectories.
*
* Requirements
* - PHP >= 4.1.0
* - GD Library ( >= 2.0.1 for good thumbnails)
* - JPEG software
* - PHP >= 4.3.0 or GD < 1.6 for GIF support
* - libpng for PNG support
*
* Installation
* Simply put this script in a folder of your web server and call it in a
* web browser. Be sure that the script has permission to read the image
* files and to create and write into the thumbnail folder.
*
* Attention:
* This script tries to generate jpeg thumbnail files in a subfolder of the
* gallery folder(s). The filenames look like "originalfilename.thumb.jpg".
