Hi Stuart,
I can see three images in your photo library, all the same as your profile photo. I just added a few photos and found that the main "Add Photo" link doesn't always work. However, the "+ Add More Photos" link at the top of the Create Album screen works fine.
I'm going to ask the techs to look into the issue. In the meantime, even if you are only adding one photo, use the + Add More Photos link.
