So is posting a photo of a dead person laying on the street on the MacResource forum is ok now?

Ideally, a photo should not be ambiguous - it also should stand on its own as a storytelling element. The word and the photos should work together to explain the story, not to explain each other. Each element should be able to stand independently of the other. But together they should exceed the storytelling of each alone.

That is not always possible but in the strongest visuals, it generally is.
