I like sigs, and these are smaller than most forums im on, but its ok. There SHOULD be a limit to basically, if you want the full 500x100, get your own webspace for it, and you cant have anything else. When people start putting quotes and crap in thier sigs and the 500x100 pic it gets messy… But avatars are prety good all around, just force people to find a place to upload it to, and it wont hurt your bandwith…
