I keep telling myself I need to make some for the lesser represented icons but I always end up back at Jack.

I just get too lazy to go digging up screencaps for the other characters. Besides Jack I've done Sam (with and without Jack, lol), Daniel, Jacob, Vala, Rodney, Ba'al, Janet and Harry Maybourne (although that was episode related he was in quite a few of them... I love Maybourne). Plus a few random other ones thrown in but those are like just one or two icons for each character.
