Careful with this one - can be slippery when wet. Do you need to know how to put this on your desktop? You can set the wallpaper as you desktop in a number of different ways. 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 you need to go to where your computer's operating system display settings and set the image as your background / wallpaper.
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 think you have it in you. My guess is you already know. I'll button it now.
