There are two types of JPEG, the normal ones, and the new 2000 format.
JPEG 2000 I believe supports CMYK and lossless compression, but the
images do not display on any browser I know of. This has caused a lot of
problems with CMS's that I've put together, as the images aren't
recognised by GD either, so I couldn't even change them. And a lot of
clients didn't even realise they were using the wrong type, as they were
just using the same images they use for print.
