you sound shocked!
my board users love placing images in their signatures, but man, do they abuse the priviledge. i've constantly had to monitor the image size... its awful.
honestly, if there were a quick and easy way to simply duplicate the entire avatar process for use in signatures, i think that would be the perfect solution.
the avatar setup already gives admins the ability to limit file size and dimensions of the image -- as well as logically just being a single image (instead of users plopping in 5-20)
controlling the actual image location would be nice, as well. if all of the sig images on my bards came from my server, we wouldn't have to wait 5 hours to download all the various photobucket accounts
and plus... its already set up!!
all one would have to do is figure out a way to call in a second "avatar" for the signature area, and its done.
