Mod-rewrite shortening imagelink
===

I have a image gallery and I would like to have a bit shorter links.


So far I have:

http://site.com/up/fjr5Z <-this shows only the image

http://site.com/images.php <-this shows all the images in html page

This is my .htaccess file and all my images are at **http.//site.com/up/**

    RewriteEngine on
    RewriteRule ^img/([^/\.]+)/?$ images.php?id=$1 [L]

I'm trying to get images work like this: **http.//site.us/fjr5Z**

Am I even close?
