Yeah, it was a dumb idea and I'm glad I brought it up here. We've
decided to just recompress the jpgs (which are usually completely
uncompressed to start with). Even a modest compression seems to save
megabytes of space. I'll try a few images to see what the best level is.
Other than that, we won't change anything.
Back to the original question ....
I think the info you need is (generally at least) in the jpg file
(Google for "EXIF data"). A while ago I wrote a library to extract the
EXIF data from jpeg / tiff files.
Oh dear, I forgot all about your library! Sounds like exactly the thing.
Thanks very much for the nudge.
