Careful with this one - can be slippery when wet. I suppose you what to know how to get it on the desktop now. There are a number of ways to set the chosen wallpaper as your desktop wallpaper / background. 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!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'. It'll come to you when the time is right. A walk in the park for you. You probably already know in fact. I'll zip it for now.
