So you like the look of this one do you? I suppose you what to know how to get it on the desktop now. You can set the wallpaper as you desktop in a number of different 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! Then go to wherever you set the background for you particular computer / operating system and select the image.
Alternatively, when the full screen image is up, right click it and select 'save image as...' or 'set as Desktop Background' or 'Set as Background'. It'll come to you when the time is right. I've never felt so sure of anything. In fact you probably already know. I'll keep it shut now.
