Hmmm, somehow I doubt that's true... Why wouldn't they be protected?
Because it is not a breach of copyright in the same way that taking a photo of a celebrity or clothes does not breach their copyright! Find me a law that says it does and I will agree. If you take someone's photo then they are not protected by copyright law but other laws.
The original copyright law was about copying text for books since large publishers were going out and selling copies of smaller publishers.
EDIT: Check #1 of the copyright FAQ
; a doll would come under artistic works but whether it can cover a photo is a different story all together.
