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! Then go to wherever you set the background for you particular computer / operating system and select the image.
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'. You'll have a flash of inspiration when the time comes. I think you have it in you. I bet you've figured it out already. I'll be quiet then.
