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 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! Next goto your computers display control panel and set the background to the image you just saved.
A different way altogether is to right click the background below, from here choose 'save image as...' or 'set as Desktop Background' or 'Set as Background'. You'll know what to do when the time comes. I know you can do this. You probably already know in fact. I'll keep it shut now.
