Possibly one of the most intersting ones on the site. Yawn! I suppose you what to know how to get it on the desktop now. 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! 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 will understand what needs to be done the the moment arrives.I believe in you. In fact you probably already know. I'll keep it shut now.
