The anti-right click scripts are foolish, because 
they're useless against those of us who a) use Macs 
(can't tell us not to right click when we don't 
have right mouse buttons) b) know how to disable 
javascript c) know how to view source anyway.  

The best solution is to watermark your cels; in 
Photoshop, create a text layer that reads "foo cel 
gallery blah blah url" and place it over your cel 
image, in a location that won't obscure the image 
but also isn't easily cropped out.  Set the layer 
transparency to 50% (it's in the layers palette), 
flatten the layers, and you're good to go.
