Now that signature images over 30KB are disabled, I was wondering something. Could the signature image code be modified to allow images hosted offsite if they are within the signature image size standards? I spent several hours too many pulling video and making an animated sig that I wanted to host offsite, only to find that I couldn't use it.
I don't know if this would be possible or if it would turn into something that would be abused. I've noticed people linking to offsite animated signatures in their sigs, but I think there could be a better option.
