Careful with this one - can be slippery when wet. I suppose you what to know how to get it on the desktop now. Getting the wallpaper onto your desktop background can be done in a number of ways. 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!Then go to wherever you set the background for you particular computer / operating system and select the image.
Another way is, when the full screen image 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. I reckon you know already.I'll keep it shut now.
