If I follow your logic, when you own a cel then 
you should have the possibility to sue the 
studio who made that cel because they used a 
picture of an item that belongs to you in a 
show ? ! ? It doesn't make sense. You have a 
cel, but no right at all.

Come on, we are just talking about (more or 
less) cheap pieces of plastic used to create 
cartoons, not a Van Gogh. From the moment the 
guy doesn't say he owns the cel or doesn't try 
to make money with it, I see no problem at all. 
Moogle is right, if you don't want your pictures 
to be stolen, don't show them.

I believe you have no right on your own scan, 
because it does NOT represent something that 
belongs to you: you DO own the piece of plastic 
+ the paint that is on it, but those 2 things 
are not visible on a scan, where you just see a 
picture of a character. And this character is 
the property of the studio, NOT yours. This is 
where it gets hard to understand, but this is 
due to the nature of cels...

If you took a picture of your cel 2 meters away 
from it and that everyone could see it's not a 
character, but plastic + paint on it, it would 
be different I guess.
