I don't know why such an easy thing as a mime type registration > hasn't been pursued to the end, but I asked on ietf-types@iana.org > about them (answer pending). http://www.jpeg.org/public/wg1n1807.txt contains the mail apparently sent to IANA by the JPEG registering image/jp2. Problem is: That document seems outdated, too. The 12byte signature given in section 4 does not match any of the JPEG2000 files I have found (it's always 2020 instead of 1a1a - some kind of versioning?)... So unless your request to IANA yields a proof for the official existence of the image/j2k type, I will remove the support for this type from KDE CVS at the end of the week. Michael
