Load images from your computer, or load images from any of the online providers that DisplayFusion supports (Bing Image Search, deviantART, Digital Blasphemy, Flickr, Google Images, Vladstudio, Wallpaper Abyss, WallpaperFusion, Zenfolio, or a directly specified URL). Once you load an image, choose how you want it scaled (crop images, stretch tile.. etc) and adjust the image's colour (normal, sepia, black/white... etc) to suit your tastes. Apply your changes and DisplayFusion takes care of the rest.
Optionally, you can have the Windows Lock Screen image change with your current Desktop Wallpaper.
