With a busy forum it'd be very nice to be able to control signatures a bit more. It got to the stage where people were having huge images in their signatures and apart from turing images off completely I'm not aware of a way to limit the file size for images in sigs.
If it was just one or two people then obviously it's up to the moderators to handle but when it's a few hundred images and having to check the size of each one it'd be nice to have a system in place to control it and I don't imagine it'd be that difficult for someone who knows what they're doing considering the code is already used for avatars.
