Just some tip in case you wish to download a wallpaper from Bing.com by using the Bash shell command.
The following wget command will download current bing.com wallpaper and save the image as wallpaper.jpg:
$ wget -O wallpaper.jpg "http://www.bing.com/$(wget -q -O- https://binged.it/2ZButYc | sed -e 's/<[^>]*>//g' | cut -d / -f2 | cut -d \& -f1)"
