Other than the earth-from-moon pic, those are stupid pictures. If the point is to educate aliens about us, they're pointless. For example, you can't tell that the rocket is a rocket; it could be a building with a bright light at the base.
We could have included: pictures of major life forms representing the major phyla, xrays of H. Sapiens, family groupings, a modern weather satellite picture, a political map (aliens would realize the boundaries are artificial, not natural, and assume we divided up the world), and so on.
