With over 3 million downloads, these beautiful, close-up Nature Images grace the desktops of computer users everywhere, and they’re now available for your iPhone or iPod touch.

We’ve partnered with a photographer whose work is included in major operating systems and whose photos are among the most popular wallpaper images in the world. Only the best images have been selected and each is carefully optimized to fit the exact specifications of the iPhone and iPod touch screens.

Nature Images contains 108 photos that have been curated to provide a perfect balance of color, contrast, and composition, so you’ll have a wide variety to choose from.

Once you’ve selected an image, save it to the Camera Roll of the Photos application where you can easily set it as your Wallpaper (simple instructions are included). Then, the selected photo will appear on your “unlock screen” and whenever you receive a call from someone who doesn’t have an associated image.
