Wallpaper Library Item

The new Wallpaper Library Item lets you set the wallpaper that will appear on the lock screens and home screens of iPhone and iPad devices you manage. To do so, you upload an image file to the Library Item. That Library Item will make recommendations about image sizes, aspect ratios, file types, and file sizes and provides previews of what the wallpaper will look like on your selected device type. For more details, see our support article.
