Is there a way to get Bing's photo of the day?

Is there some way I could get the Bing background image programmatically?

Bing's API doesn't seem to provide such functionality, perhaps there's another way?

I think the best way is immitating the way they do it themselves through their AJAX calls.

They call this URL and extract the information through XML deserialization.

XML: http://www.bing.com/HPImageArchive.aspx?format=xml&idx=0&n=1&mkt=en-US

JSON: http://www.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1&mkt=en-US

RSS: http://www.bing.com/HPImageArchive.aspx?format=rss&idx=0&n=1&mkt=en-US

The mkt attribute can obviously be changed to a different region than ´en-US´, but can also be opted out of entirely if you don't care about a specific region.

Note that the _1366x768.jpg suffix that is added to the image names appears to be modifiable into different resolutions (like _1920x1080.jpg for full HD and possibly others).

Here's a dump of the data as of 9/28/2013, in XML format.
