There's a button 'printscreen' (PrtScn)on your keyboard.
Hit it, go to paint, click edit --> paste, save the image
.
You don't have to take a picture with your camera
.
Eitherway, I'm not sure how you managed to find this topic as there's another one out in the open
.
It's right...
HERE.
Try your new found "PrtScn"button there
