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.

Of course, PBM is free, and the preview versions would still be GIF or whatever the original was. -- Dave Sill (de5@ornl.gov) Tug on anything in nature and you will find Martin Marietta Energy Systems it connected to everything else.
