Actually, I got the impression from these posts 
that, "It's your gallery, so anything goes!"  
*laughs*  Really, though, you're under no 
obligation to portray your cels in any certain 
way.  There are no rules about what is right and 
what is wrong when no trading is involved.  Your 
gallery is for *your* enjoyment, first and 
foremost, and if you like the way they come out 
after a little editing, that is what matters.
