What a peach of a wallpaper don't you think? Do you need to know how to put this on your desktop? There are a number of ways to set the chosen wallpaper as your desktop wallpaper / 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! 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 you're ready - you'll know what to do. I believe in you. I bet you already know. I'll keep it shut now.
