A picture will quickly convey more information in this situation than will a written description.
A picture can be more useful in other situations as well. For example, referring again to the supplemental text, it would have been more helpful for the news cast about hurricane Irma to include pictures of what was going on, rather than having a translator that did not know what he was doing to stand in front of the camera without a purpose. An image in this case, would have been more straight forward and everyone could have understood the circumstances without leaving people out. Although people should not have to resort to pictures for newscasts, it is more wise to use a picture rather than excluding a minority group.
