Coppermine actually includes a PHP-based open source EXIF reader module in the Coppermine product so there is no external module required.
I asked Michael about using that open source reader (or similar) as you guys use an open source ZIP module within PP. He said it'd require some kind of licensing agreement to do that like he has with that ZIP library. Food for thought anyway, would certainly lessen the install configuration required for PP.
