Careful with this one - can be slippery when wet. I suppose you what to know how to get it on the desktop now. There are a few ways to get the wallpaper to be your desktop background. You can either right click background wallpaper below and then click 'save target as...' (IE & Opera) or 'save link as...' (Firefox). Please remember where you save it to!Next goto your computers display control panel and set the background to the image you just saved.
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'. When the time is nigh - you'll do it right. I have faith in you. I bet you already know. I'll keep a lid on it now.
