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

JSON FORMAT of BING IMAGE
I found a way to fetch the JSON format of the Bing Image of the day
http://www.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1
Note
n= The no of images u want( u can use Integers) ,
mkt= Your
location (example: en-US)
Here is the JSON output looks like
{
"images": [
{
"startdate": "20141214",
"fullstartdate": "201412141830",
"enddate": "20141215",

"previous": "Previous",
"next": "Next",

}
}
use the url from the images[]
and add it to 'http://bing.com'
here url is "url": "\/az\/hprichbg\/rb\/DayGecko_EN-US8730336235_1366x768.jpg"
Microsoft has recently published a Bing Dynamic Theme for Windows 7, which contains an RSS Feed with links to Bing wallpapers.
There's also a Python script which tries to load the Bing website and guess the correct image URL, but from my experience, it usually results in a lower resolution image than those offered by the RSS feed.
