Possibly one of the most intersting ones on the site. Yawn! 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 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.
Instead you could, when the full screen version has loaded up, right click it and select 'save image as...' or 'set as Desktop Background' or 'Set as Background'.It'll come to you when the time is right. I have faith in you. You know already I'm sure. I'll keep a lid on it now.
