So you like the look of this one do you? Do you need to know how to put this on your desktop? Getting the wallpaper onto your desktop background 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 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 background 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 have faith in you. You probably already know in fact. I'll be quiet then.
