Man I need help on making sigs and wallpapers but all I have is this photo explosion program and I have no clue on how to use it *manual is missing and its buggy*. Any suggestions or links you guys can pm me or sumthing? And can you guys also teach me how to use it.

I just use MSpaint. I just finished my WP, but it wont be up untill I get home(on vacation)
