I want to change my smilies directory
some other forums stealing my bandwith, but I don't want to use .htaccess to prevent "hot linking"
I only want to change my smilies directory
If I change it, my smilies are visible without any problem or???
What should I do for changing, which parts are important to be changed in admin section?

thank you
