I came across some behind the scenes photos from Young Hannibal: Behind the Mask,showing mock French police cars on location in Prague. I'm afraid I know almost nothing about French cars from the fifties and sixties, so I can't identify them.

Two police cars

One of the cars again

IMDB page for Young Hannibal

What should I do with this? The site is blocked or I can't find them...

You have to copy/paste picture address, or reclick "go" button of the address field when you get the "forbidden" message.
But I am not sure that it is a good idea to include pictures from behind the scenes...

So n/a for this topic?

I'd say yes... or we could just put these images as thumbnail on the movie page until we have image taken from the movie itself?

That's a good idea:
