Careful with this one - can be slippery when wet. 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. One way is to right click the wallpaper below and then select 'save target as...' (IE & Opera) or 'save link as...' (Firefox). If you do this - don't forget where you saved it! 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 wallpaper 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. I trust you. I reckon you know already.I'll shut up now.
