Show HN: Social photo search

I've been working on a little side project called Snapfinch (http://snapfinch.com) for the past week or so and it's finally ready to be torn apart :)

The website allows you to search for socially shared photos across multiple services. The basic idea being that an event organizer for example can use this to group photos taken at an event and then share the page to allow people to comment.

I’m still not 100% about the way the navigation works, so any feedback in that regard will be much appreciated. And any other feedback will be appreciated as well.
