It was for a while that I was on the prowl for an entire calendar year of Bing Homepage Images that I actually found them! And that too on Bing itself. Just Visual Searched the Bing UK page and got the entire plethora of images. I individually saved them on my PC and thought it could be worthwhile to share it.
Using another Microsoft tool, I uploaded the pictures on Skydrive. Here's the link:
