i agree.  ownership of a cel certainly does not 
convey ownership rights to the image.  when 
dealing with scans not made by the cel's current 
owner (as in, for selling purposes, publicly 
posted), the cel owner has about as much right to 
demand they be removed from sites as they do to 
make the same demands of screen caps featuring 
the same image.   

especially as the person isn't trying to claim 
ownership of any of the cels posted in the 
gallery, i fail to see the atrocity.
