Wallpaper Group is a way of organizing pictures and drawings on your computer or phone. It's like a folder that contains all the images that you like to use as wallpaper on your device. You can store pictures you took, pictures you found on the internet, or any other kind of art that you think looks nice. With wallpaper groups, you don't have to scroll through hundreds of pictures to find the one you want! You just need to remember which group it's in and you can get it easily.
