I came across a really interesting site called Twicsy. The site allows users to search images that people have linked to on twitter.
The site is interesting in that you can search for a topic (such as Iran) and get a page of results. When you hover over an image, it is englarged in a popout. When you click on the image you are directed to a page with a larger version of the image and tweets related to the image. Very cool stuff.
