JavaScript programs don't have access to different-origin image pixels
(without the participation of the server hosting the image).

Note that "use" is vague. A JavaScript program it permitted to paint a
different-origin image for the user to see even though the program isn't
permitted to read the pixel data.

Also note that "rights" tends to imply things like copyright. This isn't
about that. It's about exposing confidential data that is behind a
firewall or behind ambient (cookie or HTTP auth) login.
