Facebook and privacy. Did you know...?

Sort rant of sorts.

I've just discovered that if I click my cursor on the photo /avatar of a friend on Facebook, I can transfer it to my desktop? It wouldn't have occurred to me to try (and of course, I've deleted the proof after conducting my experiment), except that someone challenged me as to why I don't accept the friendship requests of anyone whose avatar is an image of a small child.

Why would someone want the photo of someone else's small child? I've no idea.

Anyway, be careful what you put on the internet. If you didn't know that anyone can snag your profile image from any of your friends' pages, now you do.
