Making FHG using CCBill Linking codes...

Htaccess support, when properly used, can also clean up those urls so they look nice and pretty. I think something like this put inside your galleries folder should work:

# Enable rewrite
RewriteEngine on
# Perform rewrite
RewriteRule ^([0-9]+)/([a-z,0-9]+)/$ $2.php?aff=$1

This should make your urls read like this:

http://www.mariahxxx.net/galleries/644425/gal01/

Might want to get an expert to help you out if you're not familiar with htaccess though.
