I've got a HUGE library of great-looking photos that I've been turning into iPhone wallpaper images. Since I'm doing it for me, I figured I'd post them for YOU in case you wanted to use them, too.
This image is sized for the iPhone 6, although it will work for any iPhone screen. You should be able to save it to your phone's camera roll, and from there, set it as wallpaper.
This edition features Red Rocks, Colorado.
