Yes they are both in the art book, which I strongley recogmend you get.
The other picture is her being carried by a certain race of creatures that lack a head, forgot their name.
I'm not sure if there is another, I know their is a sculpture of her head, which links in with the second picture.
And yes, you can hear her voice (Simply search MO movies in youtube, it should be there), altough to my memory it's more of a mock voice, as shown in cartons, you can't actually hear a real voice, or even determine what she is saying, it's more of a squigely squeek.
