Possibly one of the most intersting ones on the site. Yawn! I suppose you what to know how to get it on the desktop now. There are a number of ways to set the chosen wallpaper as your desktop wallpaper / background. One way is to right click the desktop background below and then choose 'save target as...' (IE & Opera) or 'save link as...' (Firefox). Don't forget where you saved it though! Next goto your computers display control panel and set the background to the image you just saved.
Another way is, when the full screen image has loaded, right click it and choose 'save image as...' or 'set as Desktop Background' or 'Set as Background'. You'll know what to do when the time comes. I have faith in you. You know already I'm sure. I'll be quiet then.
