Taking pictures with a drone is still a grey area. There are laws and FAA regulations as well as licensing issues that are still not straightened out. I'd be real careful about posting pictures taken from a Quad Rotor.
This is an older article and things are changing all the time, but I would still be real careful. All you need is one person that didn't want their photo taken and your screwed legally. Unless your in MA. As long as people are fully clothed it seems anything is legal down there.....
