The digital online catalog project Connecticut History Online (www.cthistoryonline.org) used jp2s for phase 2 of their project to allow both zooming in on large images (like maps and bird's-eye views), and save space on the server. (It is a collaborative project, so individual institutions are responsible for their own archival images - here at CHS we archive in TIFF currently.)
Not all of the images on the site are jp2s, just the 'oversize' items, but the ones that I have used and seen, work very well.

Here are three of them: 1. JPEG2000 does not preserve the TIFF technical metadata when converted to JPEG2000 2. JPEG2000 files are more inconvenient to OCR than TIFF 3. JPEG2000 has no browser support yet From TIFF to JPEG 2000?
