Ah his first forum, how sweet. You dont need any fancy photoshop crap like these other guys, ms paint will do fine. Mine was made in paint. Actually ms paint is one of the best programs ever produced by microsoft. Just find something you like, add text with your name or something, and then save it as a jpeg several times so that the loss of quality will make the text look blended in. Or learn photoshop like the cool cats, or just request one from the coop i guess. Youll need to upload your image, I reccomend imageshack.us, and use that link to post the picture in your sig.
And for gods sake dont put the face in your sig, youre above that, man.
