That's an interesting idea.  I don't know anything about JPEG, but I
think Jef Poskanzer's PBM toolkit could be used to provide scaled-down
or reduced-number-of-colors versions of large GIF's.  Most people
gobbling up the girlie pictures would be happy to preview them first,
I think.  (I have no first-hand knowledge, of course :-)

Of course, PBM is free, and the preview versions would still be GIF or
whatever the original was.
