On your keyboard there should be a key named Print Screen (or some abbreviation of it like Prt Scr).

Press this button to copy a screenshot to your clipboard. You can't see it until you paste it somewhere, typically in photo software.

I use Photoshop. After pressing Print Screen, I open photoshop and click New, to create a new file. I think press Control V to paste the screenshot in the photoshop image and the adjust /crop accordingly.

This method works for most graphics programs including Paint which with comes with Windows ( I just tried out). For Paint, just press the Windows key, type Paint, and this program should be listed.

Many of the screen shots were taken showing our faces on video chat with a little bit of conversation underneath.
