Flickr recently introduced a service that lets users quickly post a Flickr photo to Twitter. That's very convenient, but what if you want to do more than tweet a link to the photo? Flickr My Background automatically sets your latest Flickr photo as your Twitter background image, updated every hour.

Setup is pretty minimal: just put in your Twitter username and password, and approve the app on Flickr, and you'll be good to go. I could see this being a problem for folks who use their Flickr accounts as basic image hosting instead of an actual photography showcase. If photos are your business or a major hobby, though, this looks like a very easy way to show off your work and keep your Twitter background fresh at the same time.
