We have a rule in my house. No photos. Ever! We had an instance a few years back when my neighbour was the same, posting anything and everything all over the internet. Then she had a little bambino. More photos than you could shake a stick at. To make a long story short, it turns out some big baby food conglomerate in China was using the Bambino's photo in all sorts of adverts. She had one heck of a time getting them to stop... So therefore no photos in my house or anywhere else without my express permission.
Goodness me, imagine finding out that. That's exactly what can happen. Sod that for a game of soldiers as they say!!
