Here's a thought: if you don't want to be seen doing something then don't do it in a public place.
You wouldn't think that would need spelling out, but apparently it does.
I'm also really enjoying the fact that by complaining about the images on Google, the people concerned have made their (very minor, and already completely public) indiscretions national news. Would anyone have noticed (or cared?) if they hadn't? other than the people themselves of course.
