Many online image collections and fan sites hold large numbers of Minecraft wallpapers available for free. Some of the most popular are Novaskin and WallpaperVortex. Many bloggers, such as Andy Sowards, also occasionally compile collections of Minecraft wallpapers.
Minecraft wallpapers can come from pictures and screenshots taken from the game itself, or from independent art based on Minecraft. Wallpapers can easily be created by taking screenshots of the game while it is running. Many gamers make fan art of their favorite games and upload it online to share with the game's community. Artistic gamers who enjoy Minecraft often upload art based on the game to blogs and forums.
