This fall I did not get any good photos of changing leaves in 2013 as the weather was not really right for it so I have been using these two photos I took as my wallpaper this fall. The panda photo is actually over a year old, but it is just so nice!
If you click on an image it will open at full size. After the image loads, right-click and download the wallpaper. As they are quite large (3200×2000 pixels) they might take a few seconds to load on slower connections.
