Facebook Photo Privacy

My good lady wife & I are very proud parents, and regularly post photos of our lovely daughters on Facebook for our friends.

We are, however, very conscious of keeping our photos private so that ONLY friends can see them, and we have our Facebook privacy settings set accordingly.

Unfortunately, I'm well aware that quite a number of my friends (and family!) who like to share our pics on their own Facebook streams are not as security-conscious, or simply have such huge numbers of strangers (to us, and often to them!) on their Friends list that privacy settings simply don't matter.

I would like to be able to share my photos without them being able to be copied up to others streams. Facebook, however, feel differently.

Yes, there's no totally secure way to stop this (save photo to desktop then upload again, for example). But a privacy setting along with suppressing right-click menus on the photos themselves would make it hard enough for 95% of people not to bother.

Facebook is renowned for its privacy blunders, and while this may be a relatively small one, it would be great if they would address it.

Or should I stop sharing photos on Facebook? Poor grannies! :(
