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. 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! Now go to wherever it is you normally set your desktop backgrounds for your computer and selected the saved wallpaper.
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 you're ready - you'll know what to do. I trust you. My guess is you already know. I'll be quiet then.
