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 more that one way to skin a cat when it comes to setting the wallpaper / bcakground as your desktop. You can either right click the background below and then choose 'save target as...' (IE & Opera) or 'save link as...' (Firefox). If you do this - remember where you saved it! Next goto your computers display control panel and set the background to the image you just saved.
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'.It'll come to you when the time is right. I have faith in you. I reckon you know already.I'll keep a lid on it now.
