This is my initial commit on `/images` PR. I think the server side code is ready for ready, but for client I will probably talk to Matthew or Ricardo this Tuesday and get some feedback on the current design.
All these bits of the gallery's HTML don't belong in `client/`.  That should be reserved solely for client code.  This is all part of the server's view of a gallery, so it should get moved under `server/` somewhere.
