The Bing Dynamic theme has now been live for about 6 weeks and the collection of photos that it downloads via RSS for your desktop continues to be a terrific collection of shots from the Bing Homepage.

Microsoft posted the Bing Dynamic Windows 7 Theme and provided those photos in a high resolution format (1920 x 1200) so they would look good on most desktops.  Prior to the release of this Windows 7 Theme the photos from the Bing Homepage could be downloaded but their resolution left a lot to be desired.

Here are the last four pictures added to the collection from Bing:

Mammoth Hot Springs, Yellowstone National Park, Wyoming Aerial image of crop circles, Wiltshire, England, United Kingdom
Diver in a grotto off of Roatan Island, Honduras Coca Falls on the Quijos River, Cayambe-Coca Reserve, Ecuador

If you have not yet downloaded the Bing Dynamic Windows 7 Theme then you can grab it here.
