would employers think less of me if they go on my facebook page and find a picture of a water pipe?

To your first question just remove the pic once he has seen it. It can't have any bearing on your future employment if its no longer there.

As for your second question, yes it is possible to send a picture without uploading to a public server. Just use e-mail and add the picture as an attachment. No one will see the picture but your recipient. You can also privately share pictures via google hangouts or google talk.
