Ah - good choice - this is one of my favourites! I suppose you what to know how to get it on the desktop now. You can set the wallpaper as you desktop in a number of different ways. 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! Next you need to go to where your computer's operating system display settings and set the image as your background / wallpaper.
Another way is, when the full screen image has loaded, right click it and choose 'save image as...' or 'set as Desktop Background' or 'Set as Background'. You will understand what needs to be done the the moment arrives.I know you can do this. You probably already know in fact. I'll button it now.
