Alpho thought about it but it would be copyright from Runescape since they get skillcapes for reaching level 100 (or 99 I forget the cap) in a skill. So I believe Alpho said no to an reward.
Ohh actually thinking about it think something like that was the idea rufus and dusty helped ol for while and remember seeing something kinda along this but Not sure if it actually could be implemented well without certain problems.not sure. Would be good for only lvl100's though so not uploading/downloading many images.
