Careful with this one - can be slippery when wet. 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! Then go to wherever you set the background for you particular computer / operating system and select the image.
Instead you could, when the full screen version has loaded 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 know you can do this. You know already I'm sure. I'll zip it for now.
