Craig, first, thanks for all the help. OK, lets see if I can list all the things I tried: 1. I changed the mount umask to 000, leaving the owner and group as root. 2. I created a separate user and group for the VFAT partiions (fatuser and fatgroup. Sorta sounds like an Austin Powers movie.) I added the netatalk user, andrew, to the fatgoup group. I tried making the mount umask 002 and 000. 3. I changed the mount owner and group to the netatalk user, andrew. The umask was 000. 4. There were at least two more setups that were some combination of the above setups. With all these setups, I got the same behavior I described in my note. I did try creating a netatalk share on an ext3 filesystem. I copied the same files I was testing from the VFAT filesystem to the ext3 filesystem using "cp -rp". I was able to save the image files with Photoshop Elements. It worked fine. So the problem does seem to be specific to the VFAT filesystem. The problem may be with how netatalk interacts with the VFAT filesystem. The problem may be with how the Mac handles files. I don't know. The fact that the ext3 filesystem works gives me a workaround. It would still be nice to get the VFAT filesystem working. It would save me a couple of steps in my digital photography workflow.
