Yes, at one point I had a plugin that got the exif data from an uploaded file and saved it in a database field. Unfortunately a while back I had a number of problems on my home computer (where I work on everything) and that was one of the things I lost, so I don't have anything to give you. But there wasn't a lot to it - there's a php function that reads exif data, so I just called it on the temporary upload file if it was of the correct type. The biggest problem was figuring out the plugin hook where the right info was available, and I don't remember which one that was. I also remember there was a problem with getting it back out of the database at the right times because I couldn't find hooks in the right places. But if you only want to write something for your own site you always have the option of editing the vb files to get around that (I could have done that for a released mod as well, but I try to avoid it).
