The best thing to do, in order to get a picture of this site to your desktop is:
1. save the micture by clicking on it with your right mouse button
2. then, go to your control panel -> monitor, and it the best thing to do is choose the third option (I don't know how they call it in English, but it's not centered nor tiled, i think they call it 'spread'). Now your picture should be allover your desktop.
3. Maybe you should ask permission for putting it on your desktop, but I don't think that anybody would mind putting his picture on anybody's desktop.
