A screenshot is a picture of your screen you can take using the "PrtSc" or "Print Screen" key. If the key only has the "PrtSc" text on it, you can just press the button, but if it has another line of text below it (usually "SysRq"), then you need to hold down the "Ctrl" key when you hit the "PrtSc" key.

Once you have that done, open a drawing or photo editing program of your choice (Microsoft Paint should work assuming you only have the default installations) and paste what's on your clipboard into the program (by holding down "Ctrl" and pressing "V"). At that point, the picture from your screen should be visible in the program. Save it as a PNG or JPG file and voila, you have your screenshot.

To present credible proof in this particular scenario, you need to take a screenshot of the conversation you had with the guy whose art you're using and then post that screenshot to the wiki. Once you've done that, you'll be good to go for using the art.
