Wallpaper Master offers a number of options to renew your desktop background image. Create categories to organize your wallpapers and order your different images in a list on the interface. Individual Overrides, like style, alignment or border can be modified directly from the program window. Images can also be set up on multiple monitors in one click.
Despite a good deal of options, we were slightly disappointed with Wallpaper Master. There's no drag and drop, which means you have to browse and select all the pictures you want to use as wallpapers. The effects you can add to them, mirror, black and white and mosaic, are fairly limited and do not add much to your images.
Once you chosen the image you'll use as wallpapers and set up the rotation you can let Wallpaper Master take care of the rest. The program could be a bit more intuitive and offer more effects, but on the whole is a good piece of software to manage your wallpapers.
