Posting a Screen Shot

Does anyone know how to post a screen shot? I wanted to show someone what my screen looked like but couldn’t figure out how to get it into my posting.

Hi…Do you know how to make a screenshot? if you do, then all you need to do is attach it to your post as a picture.

I do know how to make a screen shot. But I can’t seem to paste it into this posting. Do I have to save it as a pdf first?

I save it as a picture and then attach it
