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. One way is to right click the desktop background below and then choose 'save target as...' (IE & Opera) or 'save link as...' (Firefox). Don't forget where you saved it though! Next goto where you set the desktop background for your particular computers operating system and select the image from the location where you saved it.
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'. You will understand what needs to be done the the moment arrives.I think you have it in you. My guess is you already know. I'll button it now.
