[Zope] Photo information

I'm trying to extract the IPTC/NAA caption information from JPEGs stored by Photoshop. I've noticed the IPTC plugin for the Python Imaging Library, but can't figure out how it works and can't seem to find any helpful docs on it. Two questions: Anyone know how to do this, and is it best once I've figure out that part of the puzzle to access it through an external method? Or is Zope gonna strip out the information when the image is made into an image object? Thanks! -- Chris Muldrow muldrow@mac.com cmuldrow@fredeicksburg.com
