====================================
Script Author: Ash Young <ash@evoluted.net>. www.evoluted.net
Layout: Manny <manny@tenka.co.uk>. www.tenka.co.uk

REQUIREMENTS
============
This script requires PHP and GD2 if you wish to use the 
thumbnail functionality.

INSTRUCTIONS
============
1) Unzip all files 
2) Edit this file, making sure everything is setup as required.
3) Upload to server
4) ??????
5) Profit!

CONFIGURATION
=============
Edit the variables in this section to make the script work as
you require.

Start Directory - To list the files contained within the current 
directory enter '.', otherwise enter the path to the directory 
you wish to list. The path must be relative to the current 
directory.
*/
$startdir = DIR_FS_CATALOG . $tempdir;

/*
Show Thumbnails? - Set to true if you wish to use the 
scripts auto-thumbnail generation capabilities.
This requires that GD2 is installed.
*/
$showthumbnails = true; 

/*
Show Directories - Do you want to make subdirectories available?
If not set this to false
*/
$showdirs = true;

/* 
Force downloads - Do you want to force people to download the files
rather than viewing them in their browser?
*/
$forcedownloads = false;

/*
Hide Files - If you wish to hide certain files or directories 
then enter their details here. The values entered are matched
against the file/directory names. If any part of the name 
matches what is entered below then it is now shown.
*/
$hide = array(
				'dlf',
				'index.php',
				'Thumbs',
				'.htaccess',
				'.htpasswd',

/* 
Show index files - if an index file is found in a directory
to you want to display that rather than the listing output 
from this script?
*/			
$displayindex = false;

/*
Allow uploads? - If enabled users will be able to upload 
files to any viewable directory. You should really only enable
this if the area this script is in is already password protected.
*/
$allowuploads = false;

/*
Overwrite files - If a user uploads a file with the same
name as an existing file do you want the existing file
to be overwritten?
*/
$overwrite = false;

/*
Index files - The follow array contains all the index files
that will be used if $displayindex (above) is set to true.
Feel free to add, delete or alter these
*/

$indexfiles = array (
				'index.html',
				'index.htm',
				'default.htm',
				'default.html'
			);
			
/*
File Icons - If you want to add your own special file icons use 
this section below. Each entry relates to the extension of the 
given file, in the form <extension> => <filename>. 
These files must be located within the dlf directory.
*/
$filetypes = array (
				'png' => 'jpg.gif',
				'jpeg' => 'jpg.gif',
