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. You can set the wallpaper as you desktop in a number of different ways. 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 you need to go to where your computer's operating system display settings and set the image as your background / wallpaper.
Instead you could, when the full screen version has loaded up, right click it and select 'save image as...' or 'set as Desktop Background' or 'Set as Background'.You'll know what to do when the time comes. I know you can do this. In fact you probably already know. I'll be quiet then.
