Files Lister
============
Very simple files/sub-dirs/media lister.
images get a small thumbnail, and sub-dirs are supported too.

no need to put the file in every sub-dir, just the most upper one.
you can assign a relative home-dir, from which the user cannot list out.
you can cancel the show sub-dirs option.
you can show only media files if you want.
support for up-dir (..) is cancelled for security reasons.
when a file named icon.gif/jpg/ico exists in a sub-dir - it is used as a thumbnail for the sub-dir.

Installation:
Just put the file in your home dir, and name it what you want.
Options:
parameter method options default description
========= ====== ======= ======= ===========
dir $_GET $dirdef subdir (without a slash)
media $_GET 1/0 $mediadef hide non-media files

$homedir variable the base relative home dir. u must add a slash at the end.
$mediaopt variable 1/0 1 show the option to switch between hide/show non-media files?
$mediadef variable 1/0 0 media default status, and permanent status when $mediaopt==0
$showdirs variable 1/0 1 show sub-dirs? when disabled, the dir parameter is also not available
