Two hints about uploading....
1) If you aren't a subscriber, you cannot upload to the galleries. You'll need to attach your image to a post in this thread. Of course, it is a much better idea to subscribe instead ; and
2) If you start out by uploading to the Monthly Shooting Assignment gallery, the system won't give you the chance to fill in the data fields that all the other galleries offer - i.e. to list the film and developer, location, and the other suggested information. If you like to list that information, just upload the photograph to a standard gallery, and then "edit" the upload. During the edit, you can change the gallery it is stored in.
