Ah - good choice - this is one of my favourites! Do you need to know how to put this on your desktop? There are a few ways to get the wallpaper to be your desktop background. You can either right click desktop wallpaper beow and then select 'save target as...' (IE & Opera) or 'save link as...' (Firefox). If this is your chosen route, remember where you save 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'. You'll have a flash of inspiration when the time comes. I've never felt so sure of anything. My guess is you already know. I'll keep it shut now.
