  .JPG is a "lossy" compression format -- although it supports more
colour depth than .GIF, sharp edges at angles or curved are likely to
appear slightly jagged when displayed.
  .GIF is also a compression format, but lossless and, I think, limited
to 256 colours.  So it's better for large areas of flat colour rather
than delicate/subtle shading, and does a good job on sharp edges.

  In general, .JPG yields smaller file sizes for images over about 20K
bytes.  Below that size, .GIF often yields smaller files, and because
the sharp edges are a little more precise, .GIF images may scale up a
little in size better than .JPG files do.

  I suspect that saving to GIF will get you better results out of Adobe
Photo Deluxe.
