Signature Fun

[Justice]

This is really more of a 'omg help me' question. I've got a signature image that I'd like to post, but whenever I attempt to change my signature the message 'unable to save image' pops up. The signature is smaller than 500x100 and is only 18 KB. Any clue why this is happenning?

The sig:
Faith (http://i84.photobucket.com/albums/k21/GNRSlashfan/Smallsig.jpg)

Yes. We don't allow images in signatures here, which is why you've been receiving that error. Sorry for any inconvenience.
