Section 65;
(6) Where an image shows a person the image is to be treated as an image of a child if—
(a) the impression conveyed by the image is that the person shown is a child, or
(b) the predominant impression conveyed is that the person shown is a child despite the fact that some of the physical characteristics shown are not those of a child.
