One user preferred having the view photos page and the upload photos page to be two separate pages. Moreover, when viewing updates from the main page, they wanted a link to the circle rather than only having the option to close the photo and return to the main page. They also wanted a more obvious way of exiting the photo to return to the main page when viewing updates other than just clicking outside the photo to close the box.
We also noticed that nobody tried to rearrange or delete photos. We didn't give these specific instructions because we wanted to see if it was obvious that this could be done, but we realized we needed a better affordance so users knew it could be done.
Another user asked for the ability to make captions for photos, preferring this over comments as the owner of the photo.
Finally, the last suggestion that was given to use was to allow people to create profiles for their accounts, and to allow users to view others' profiles. This gave us the idea to show your connections to other users when you click on their usernames.
