People seem to really like the daily images that Bing shows as backgrounds. And if you'd like to have Bing.com use one of your photos as a background, you're in luck. Until July 16, you can submit your photos through a Facebook Contest where the photo will be judge along with others and one winner will have their image used on Monday August 3rd. Contest rules can be found here, and even if you're not submitting a photo the contest rules are interesting to see what types of selection criteria Bing.com has for photos. There is no cash or prizes for the winner, only the recognition that goes with having your name and work in front of millions of eyes.
