A mobile wallpaper is a desktop wallpaper that has been resized to fit on a mobile device such as a phone, personal digital assistant, or digital music player. The height is generally more than or equal to the breadth. Wallpapers for current phones may often be downloaded for free from a variety of sources (such as those running Android, iOS, or Windows Phone operating systems). Modern smartphones enable users to set wallpapers from the web or from images taken with the phone's camera. Wallpaper pictures, like many other digital images accessed on the Internet, are often copyrighted.
