I don't know if many of you are aware, but there are some sick people who steal photos of children from people's photostreams on flickr and put sick profiles with them, things like "I'm Cupcake. I'm 5 years old, and single. I like oreos and walks on the beach" and all sorts of disturbing things. Even having your photos set to "no download" doesn't keep them safe from screen capture. The only safe way is to keep your photos friends and family only.
