karohemd | Attention flickr users

This photo is visible to all:

That's interesting, because this photo is marked as private on flickr.
It's also disconcerting, as I previously thought that setting a photo private will make it invisible to anyone else and checking friends or family will make it visible to flickr users that are defined as friends or family. This might be the case within flickr but not for links posted on external sites.

I just checked the flickr FAQ and it says:
What if I don't want everyone to see my photos?

That's not a problem. Every photo comes with its own privacy settings. You can make a photo available to everyone (That's public, and includes people visiting the site who aren't Flickr members), only make it visible to people who are your friends, just to your family, to both your friends and family, or you can keep an image completely private.

It doesn't mention that copied links will still work...
