What operating system are you on?
If you're on windows, press PRNT SCRN at the top right of your keyboard. And open your image editing software (Photoshop, Gimp, MS Paint, etc), and click paste. Save it, and upload it to a hosting site such as Pwnjoo, or Imageshack.
If linux, just PRNT SCRN.
If Mac, ...I don't know. You have to hold like 5 keys.
