Oh no - this one's a stinker! - not really. Do you need to know how to put this on your desktop? Getting the wallpaper onto your desktop background can be done in a number of ways. 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 where you set the desktop background for your particular computers operating system and select the image from the location where you saved it.
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'. You'll have a flash of inspiration when the time comes. I believe in you. My guess is you already know. I'll be quiet then.
