* This file creates a directory listing for various pages in my images subdomain.
* It will display all files loaded into the directory except for: '.', '..',
* 'index.php', and 'style.css'. Everything else is fair game. The script will also
* create a link to the file specified for easy access/viewing.

* Update: 08 December 2004: Modified to be XHTML Transitional Compliant.
* Update: 01 August 2005: Tweaked certain items to go
* with new layout.
* Update: 17 February 2006: Changed include statements (sort.php, footer.php)
* so they will be compatable across different servers.
* ( using $_SERVER['DOCUMENT_ROOT'] )
* Update: 20 February 2006: Modified the if-statement of items not to be included
* into the directory list by converting it into a switch statement. Also added
* more file names to not be included. Converted the function calls to sort.php
* into a switch statement. Modified the session conditional statement to make
* it more efficient.
