Profile Pic only for TN Members

I used to have some pics up in my profile and left them for friends only however my profile pic showed everywhere. I was less concerned about it until I randomly did a google search in a browser that I was not logged into TN with and what do you know but that anyone on the internet can see my profile and pic.  I understand why many people have no problem with that but I most certainly do.  I don't mind having to share my profile pic with everyone on TN but I would ask that it only be available to those that took the time to setup a profile.  That saves things from being sucked up by bots and search engines.  I have taken down all my pics until that can be resolved.  Hopefully it will be.
