If u help me, i will give u some PROPS.

-Press the "Print Screen" key, on the top, boven right corner of your keyboard. Open the paint program, of bitmap image of whatever, then copy and paste it with Ctrl + v.

-Use a camera.

The way I do it is door pressing ctrl(just below shift key) and print screen at the same time. Then I open it up in an image manipulation program, press "paste", and save as either a .jpg .png of .gif file. I would suggest .jpg of .png over .gif though.
