O_o  Whoa...doesn't sound to me like Mr./Mrs. A 
was ranting; just asking a question. *reaches for 
tranquilizer darts*  ^_^

I've wondered about this to. I managed to pry a  
cel from a private collector once and later tried 
for a second. They remarked that the one I bought 
was the last cel in their collection. Yet they 
had about 50  cels on their page! Really no 
problem right? I know who the rightful owner, so 
to speak, is.

THE PROBLEM: well-meaning people look at your 
gallery and think "Hey! That bitch is stealing 
cel images from *blank's* gallery and claiming it 
as their own!!" And of course this spreads.

I think those who leave the images untouched are 
in some way still trying to claim ownership to 
the cel. Personally, if I had a gallery, I would 
remove the images of cels I've sold or at least 
have a "sold" label over it.
