So you like the look of this one do you? 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. You can either right click desktop wallpaper beow and then select 'save target as...' (IE & Opera) or 'save link as...' (Firefox). If this is your chosen route, remember where you save it! Next goto your computers display control panel and set the background to the image you just saved.
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'. When the time comes - you'll know what to do. I believe in you. In fact you probably already know. I'll shut up now.
