Hi there Nor'easter,
The first thing that is needed is an album. If you haven't got one, send a note to Mike or Bill, the administrators, and they will set you up with one. After that, you go to "Album Actions" and select add photos. There are a number of threads on this topic, so if needed, you can get more detailed help than what I am providing.
If you are using a Mac, Firefox seems to work better than Safari. That is, it works.
