To set an image as a background or to save it to your hard drive follow the link to the preferred screen resolution, eg. 1680x1050 (find out your screen resolution: right-click on your DESKTOP and select the "Properties"-option, then select the "Settings"-tab where your screen resolution will be displayed at the bottom-left next to "Color quality"). Right-click with your mouse on the downloaded image – you should see options such as "Set as Background" or "Save Picture As..." – and choose the option you want.
