 Script Isaac.php

 Author:      Neven Mrgan [neven@mrgan.com]
 Date:        May 2002 - October 2003
 Description: Image viewer and directory browser
 URL:         http://tosviol.net/isaac

 Use:

	Simply place the file in any directory (preferrable, the one you want to use as "top-
	level directory"), edit script preferences below if desired, and load. Please refer to
	the URL for documentation and updates.

 System requirements:

	This script is distributed as a single standalone file. It has been tested on a Win
	platform running PHP 4+ and should run on most servers with PHP installed.
	
Disclaimer:

	This script performs well in everyday use and can be easily modified if you are familiar
	with PHP. If you are not, or if you will use the script for a serious purpose, I can make
	no guarantees. Please contact me should you experience any problems [neven@mrgan.com].
