Max overall height 250px - if this is exceeded, a scrollbar will appear on your signature. (Enforced at 1280px window width) Max image width 550px - no images wider than 550px but the overall signature can be as wide as you like Unlimited number of images - no fixed limit, but please keep within reason (certainly less than 10). Above rules on images do not apply to images inside spoiler tags. These rules are in immediate effect - the situation with signatures is getting majorly out of hand.
