Oh no - this one's a stinker! - not really. 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. 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! Now go to wherever it is you normally set your desktop backgrounds for your computer and selected the saved wallpaper.
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'm routing for you.You know already I'm sure. I'll keep a lid on it now.
