JPG?? MP3?? Sounds like you need a "Business Only" policy! I put this together for a client some time ago to analyze network home folders. They were amazed/shocked/appalled to find that nearly 45% of the SAN space was consumed by personal media - photos, music, videos.

They created a business policy that forbade storing any media on the home share. Users that had a business reason (advertising & presentations) for such media were required to store it on the department share. An announcement was sent to all users. Media on this share were excluded from backups. A series of emails reminded people to remove all personal media from their home share before we began deleting it.

I'll see if I still have any code from that project that you might be able to adapt..
