  I wonder if it would be a good idea to add something in the lines of
requiring the quality of the image not having been destroyed too much
by the JPEG compression.
  I know that it's only foolish to submit an image which would be
otherwise excellent but shows bad JPEG artifacts, but it may still
be a good idea to add a reminder that the submitter should be careful
with this and not just accept whatever default compression whichever
program he is using offers him, but should fine-tune it so that the
image shows no visible JPEG artifacts (while still being as small
as possible; that is, the submitter should try to find the compression
setting that gives the best quality/size ratio).
