And the article on Obstetric ultrasonography contains an image of an obstetric ultrasound This isn t the article on obstetric ultrasonography A couple of other articles use the cartoons as well some but not all in contexts I think are unnecessary but guess what It s possible to stay on topic The images are used to prejudice people in favor of one particular choice They don t contribute anything essential to the article because people can click links if they want to know what an ultrasound looks like There is no reason to include them talk contribs
