Look at doing it with php. Rasmus said at his talk here a couple of weeks
ago that they have a library for that :). He mentioned what the embedded
info in the images is called, but I don't remember what it is. If you have
that term, you might be able to better search for info on it. I'd think
there's be a perl library to handle it. If not and you have the specs for
the standard you could grep out the info you want by hand.

See http://www.azphp.org/ for info about Rasmus' talk. I thought they were
gonna have a mpg up there, but don't see one. There is a link to his
presentation, the info should be in there.

ciao,
