How do I take seti screen shots?

I found a signal its it I know it Im looking at this right now how do I know where the arrays facing I found a signal Im not hoaxing.

use your print screen key, then open what ever image program you have and paste it in then save it

If you're using windows hit control and print screen, then paste the image to paint or another graphics program.

Hope that helps.

I have photos yes there double bars its a signal I think. Im going to photo bucket.
