If you love the backgrounds supplied on ChromeOS by default then you may have noticed a recent update which added 28 new images to the Wallpaper Picker. The images from photographers Trey Ratcliff and Greg Spencer are beautiful and show some very interesting scenes.
The wallpapers available in the Wallpaper picker in ChromeOS are all kept online and are shown as a preview until you choose to use them, at which time they are downloaded and stored locally. If you check in your Wallpaper Picker you can see these latest wallpapers now.
As a personal choice I tend to use the ChromeOS wallpapers on my Chromebook, however I tend to use a blank black background on other operating systems. Perhaps in response to the storing of files and shortcuts on the desktop.
Do you use the ChromeOS wallpapers or import your own?
I use the same wallpaper as on all my nexus devices.
