The photo is supposed to be enlarged when you select it as wallpaper, this is so that when the parallax effect is turned on, there are no black borders between the edge of the photo and the edge of the screen.Yes when I pull the photo over it's to big for the screen and it want let you move or scale the photo
The sharper the better. Personally, I use photos taken with my 16 MP digital camera, it has twice the resolution of an iPhone 5S camera.What size is the resolution that will work as wallpaper?
