How to prevent people I don't know on facebook from seeing my photos?

[Just Google it.]

go into your account - privacy settings - change everything to "friends only" instead of "anyone" or "friends & networks"

All this is located on the right side of the blue facebook banner.

Go to privacy settings and click friends only, also you can make your profile private as well, so only your friends can see it!
