Though it is indeed rude of the photographer to take photos without permission but legally speaking, there is nothing wrong with it.
Now that you've mentioned this, perhaps he/ she will not even admit being the photographer :bsmilie::bsmilie:
As for the photos, it is rightfully yours (unless it is an unpaid shoot which I doubt so). There is nothing wrong for you to post your own photos online.
Cheers
Nothing wrong legally meh? You go stand in front of any security guard, wait for him to look at you, then whip out your dSLR with long long lens, he'll probably have different ideas of what constitutes legal. hahaha
