Add photo credit to the website

[yokolet]

Since we use photos from flickr, we need to credit photo owners.

Old website will have small flickr icon(s) on the bottom of the top page. Each of those are links to the photo website on flickr.

Maybe, we should add another page to address credits? If a bunch of icons are lined up on the bottom, it would be ugly.

We could add a small link at the bottom of each photo, perhaps.
