I'm not sure how useful JPEG2000 is. The lack of a widely available
software library and it's patent encumbrance has slowed it's incorporation
in a lot of software, and whether the high level of complexity justifies
the gains is a good question. One technical evaluation I read found that
while JPEG2000 gave better quality at very high (lossy) compression (very
low quality), that at high quality settings, standard JPEG gave better
results for a given file size. It would be interesting to verify this
finding at some stage.
