Actually, I would love to... But there is no API to get images from Bing.com
If you look at the source code, you can see that I actually parse the html to find the background image.
So even the slighest change could break the app. (However I'm ready to play a cat and mouse game :D)
If you want to view the archives of all Bing Images, you can visit, LongZheng's site @
I'm working on a backgrounder kind of app that automatically runs bingdownloader at a specified time everyday. so that you can get all wallpapers from today.
I also have made another app,
this changes your desktop wallpaper automatically picking images from a folder.
Just map the "BingImages" to this app and you can see Bing Wallpapers on your desktop... :D
