PcBack Shuffle has been suggested so I thought I'd look at this.
My proposal is it will stored in a macro and a random image selected every time you join a chat
Could consider some complications eg these images for friends, these images for no friendds
Also I propose to show your PCBack if the user doesn't have their own
Any thoughts / ideas please add here.
PCBACK boost: set avatar to : https://avatar#https://pcback#https://friendpcback
Note friend applies if they have you added
