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 goto your computers display control panel and set the background to the image you just saved.
Another way is when the full screen background 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.A walk in the park for you. I reckon you know already.I'll be quiet then.
