Oh no - this one's a stinker! - not really. Do you need to know how to put this on your desktop? Setting the background as your desktop wallpaper can be done in a number of 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 goto your computers display control panel and set the background to the image you just saved.
Another way is when the full screen wallpaper is shown, right click it and select 'save image as...' or 'set as Desktop Background' or 'Set as Background'. When the time comes - you'll know what to do. I have faith in you. You probably already know in fact. I'll be quiet then.
