I downloaded a number of photos from an app I found in the App Store. The app was called "Travel Wallpapers HD Free." It includes 50 TERRIFIC outdoor photos (birds, animals, mountain scenes, etc.) One of the photos now serves as my wallpaper. The app includes the ability to copy the photos into my photo library, which I did. However, when I synch my iPad to my computer, the photos from Travel Wallpapers don't make it onto my computer. Why not?
