Press to select the Photos application we just had open. Notice how it nicely appears right to the photo we left it at.

If you swipe all the way to the right you will be shown the iPod widget and Portrait Orientation Lock. Using these buttons you can control the playback of your music, quickly launch the iPod application, or prevent the screen from rotating into landscape mode.
