I've added the ability of seeing who liked your photo when you click on the like counter. Hopefully this is still useful once there are hundreds of likes on a photo, but we'll see when we get there.
I've also created pages for different camera brands. They come alive once a camera type has at least two photos associated with it, and are accessed by clicking on the camera type from any photo, or from the "Shoots on" section of member profiles.
