Please reserve the upload system for fruit-related photos that you wouldn't mind being placed in the photo gallery. Put your name and comments such as tree species in the filename, because I didn't incorporate a comments system into the photo upload.
I am not aware of a NAFEX area to which photos can be posted. I believe that when you see links to photos in posts, the photos have been posted to either a poster's private (but publicly readable) web space, or to
one of the various photo hosting sites (e.g. www.google.com/base)
