Export image with metadata ON image?

Hi all. So here's a question for you. I am doing some tests with a new camera.  I would like to send a few of my test exports off to a few friends. I would like to include the camera settings (f-stop, ISO etc) on the image like a watermark. Is there a way to do this in Lightroom? I know they can just right click and look at the metadata, but I would like to make it easy as possible for them. 

Has anyone found a way to do this?

Thanks!

Andrew
