Thanks Glen, the one big down fall to a .gif Sig is you do resolution and picture quality, but they do look cool. I have a static version of my ghostbusters Sig that looks really nice but I decided to go with the animated one for the cool factor lol.
Tony have looked at Gimp? its free and what I use to create all of my Sig's and do other photo editing with it too. http://www.gimp.org
here is the static version as you can see when you animated it you loose alot of the glow and shadow effects and image quality.
