*	Description: This file(index.php4) is the complete galleryscript, it includes    *
*                everything! It's complete based on functions. 						 *
*				You need simply fillin some informations into the variables the 	 *
*				config-part of this script below the changes-section, like this:	 *
*				$pagetitle = "fillin the pagetitle here";							 *
*																					 *
*				What what is this script good for?									 *
*				Very simple to explain. It will build a dynamic gallery with 		 *
*				thumbnails-support. Every image of the types JPEG and PNG which is in*
*				the same directory like this index.php4 will be shown as a thumb in  *
*				the gallery. If you click on it it will be resized to a specail size *
*				and gets displayed in a popup window.								 *
*																					 *
*				Is it possibel to rename the index.php4?							 *
*				Yes! Will operate in every PHP supportet filename.					 *
