It is proven that, as much as you like a desktop background, always, after a while, you end up getting bored and tired of it, so that programs that are exchangers of funds, such as this WallPapa, are increasingly imposed.
WallPapa backgrounds can be changed manually or automatically (although this last option is more convenient), allowing you to load any image that is in the following formats: BMP, JPG, PNG or GIF. The backgrounds can be displayed in the center, stretched, scaled, tiled, and so on.
You can configure WallPapa to exclude or include certain images in the subfolders you are looking for. If the image to be displayed as a background is too small, then WallPapa puts it directly in mosaic mode.
You can free download WallPapa 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
