Legal, schmegal – Photography rights challenged, again!

I thought this was going to be a slightly alarmist story about the heavy handed nature of the law when I read “riot act” but it turned out well enough in the end.
Almost on topic, I remember taking a photo of a dramatic painting in the Louvre years ago. I thought I had disabled the flash, but no, I hadn’t and bright white light poured into the room when I pressed the shutter button!
No sooner had I realised my mistake than an irate lady came pounding up to me gesticulating wildly and berating me, in French, for destroying a work of art! Unfortunately, my French was only slightly better than it is now (and that extends to about a dozen words!) but I didn’t need a gift with languages to realise what she was saying! *gulp*
I still have that photo at home somewhere..
