I think that would be okay.  For high-quality images, such processing  
is best done manually or with a dedicated tool chain  
(ImageMagick...).  One could remove the reference to the original  
image as soon as any kind of processing is done in order to maintain  
compatibility.

I'm working on a patch to see if this is doable.  I'll get back to you  
once I've tested it.
