That would be a huge loophole in the GPL, if you could get away with
not making your source public, by saying that you're only required to
make public the form of the work which is already public.

I'm not sure what that has to do with anything. If I take an SVG
image and make a PNG out of it, it seems obvious to me that the SVG is
the source, not the PNG. If I take an SVG image which is under GPL,
modify it, make a PNG out of it, and distribute the PNG, I have to
(offer to) distribute the SVG, not just the PNG.

Whose intention? I assume you mean the intention of the FSF, as
compared to the intention of CC. The FSF's intention and philosophy
is quite clearly very different from that of CC.

Why do you assume I only have the image file? Why do you assume I'm
even talking about a file? Maybe I'm talking about a printed
photograph. What if the file is shrunk from the original?

That depends quite a lot on the type of work.

And if the source is a 19 gig xml file and the image is a 19K PNG file?
