It has now been a little more than a month since Microsoft posted the Bing Dynamic Windows 7 Theme which adds Bing homepage photos to your Windows 7 system in a high resolution format (1920 x 1200) so they can be displayed on your desktop.  They update the pictures available in that theme using an RSS feed that your Windows system periodically checks and downloads the new photos from.

There are a total of 15 wallpapers in that collection now and I thought it would be good to summarize what is available up to this point.
