Oh no - this one's a stinker! - not really. I suppose you what to know how to get it on the desktop now. There are a few ways to get the wallpaper to be your desktop 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! Then go to wherever you set the background for you particular computer / operating system and select the image.
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'. It'll come to you when the time is right. I've never felt so sure of anything. I bet you already know. I'll shut up now.
