It's a free art program that you might like and can use when making stuff for your site.
It's call Gimp and you need both parts for it to work. Also you might want the animation pack at the bottom of the page.

This site will help you learn the program, has tutorials, how to download scripts, and a message board you can ask stuff on.

I made this with it. Had to download the font and some extra brushes though.
