Description:
============

The FileDisplay class will show a directory listing of folders and files
in a specified root directory.  (actually only images and folders - if you
alter the checkext method, you can display all or a limited selection of
files) 
The class adds links to each subdirectory.  When you click on a subdirectory,
the page reloads and the contents of the subfolder (including any subdirectories)
is displayed.  You can display an endless number of subdirectories, but the
filepath from the root directory is displayed at the top of the page, so the
formatting might get a little messy if you explore too deep!


Installation:
=============

Upload the FileDisplay.inc.php file and the images to your web server.
You will need to create at least two icon images (1 for files & the other
for directories) and put them in the same directory as FileDisplayClass.inc.php.
Apache has some good images in the 'icons' directory.

Configuration:
==============

See accompanying file - test_FileDisplay.php
For explanations of each of the methods of the class, see the comments in
FileDisplayClass.inc.php


Security:
=========

The target folder information is contained in the query string.  So that users
don't enter ../../ in the querystring and explore your entire file system, the
code checks that the root directory (a directory of your choosing) is a sub 
string of the target dir. 


Last Comments:
==============

This is the first class I've submitted.  I know it doesn't do anything
revolutionary, but it's simple, self-contained and meets the needs for which
I designed it.
If you have any fixes, suggestions, rewrites, additions, please let me know.
