Oh no - this one's a stinker! - not really. Do you need to know how to put this on your desktop? There are more that one way to skin a cat when it comes to setting the wallpaper / bcakground as your desktop. One way is to right click the wallpaper below and then select 'save target as...' (IE & Opera) or 'save link as...' (Firefox). If you do this - don't forget where you saved it! Then go to wherever you set the background for you particular computer / operating system and select the image.
Alternatively, when the full screen image is up, right click it and select 'save image as...' or 'set as Desktop Background' or 'Set as Background'. When the time is nigh - you'll do it right. I think you have it in you. My guess is you already know. I'll zip it for now.
