No, the photos aren't here and clearly there an argument of Invasion of Privacy (there's lots of Press for and against the release of the photos).
My initial reaction was that was an invasion of privacy and that's it. However, the counter-argument that in France the royals are treated no differently to other celebrities (fair enough, they got rid of their royal family a long time ago) got me thinking... if the photos were of a UK celebrity (maybe a singer or actress) would we say the same, or would that be considered fair game? It's almost as if laws have to become a lot more international to make them stick. There was a press lockdown on whether it could be reported that the son of an MP had taken drugs. Since it was reported in Scotland where the laws are different, and was available on the Internet it became a bit of a nonsense.
I'm actually coming round to the view that the only thing you can do is apply the rules and laws that apply in that country - it would be consistent after all. From the photographer's perspective it's always important to consider the social etiquette of the country you're traveling in (not that I'm claiming the way of things in France is to be a peeping tom with some super massive zoom lens).
