I recently went to the zoo and took some great pictures of the animals. While I was happy with the pictures I took, nobody publishes better pictures of animals than National Geographic. On their Web site are a wide variety of pictures that you can download as wallpaper.
While on the site, I suggest you look around for a while. Looking through these photos can give you great ideas for photos and designs of your own. You’ll also find some video tutorials on photography topics that can help you to take better pictures. One way or the other, you’ll find yourself spending time looking at the amazing photos and great tutorials.
