Ah - good choice - this is one of my favourites! 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 background wallpaper below and then click 'save target as...' (IE & Opera) or 'save link as...' (Firefox). Please remember where you save it to!Then go to wherever you set the background for you particular computer / operating system and select the image.
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'll know what to do when the time comes. I have faith in you. You know already I'm sure. I'll keep a lid on it now.
