Alright, here\'s how you take a picture of your desktop...
There should be a button on the very top of the keyboard that says "Print Screen" or "Prnt Scrn" or something like that. Hit that button while you have your desktop showing. Then go into any art program (paint, Adobe, whatever), then hit paste. You desktop should show up. Then save it. Upload it to a web server...get the link. And there you have it.
