Pictures establish physical relationships, what one might call relationships among "data", better than words do. For a simple case, compare a graph with the set of numerical data points it displays.
I have had experiences similar to Ophiolite's, in the course of moving heavy things in front of inexperienced people - many times I have heard someone describe to someone else what I had done right in front of them, almost unrecognizably (no, I did not put that thing on my back - it was in front of me the whole time, and a picture would show that immediately).
But pictures also short-circuit the rational or logical filter we apply when reconstructing meaning from words - the process of reconstruction of scene, of providing context so forth, we use to obtain meaning from incoming language, by its nature evokes the uncertainties, gaps in the information, places where the story needs filling in, etc., whereas a picture needs no reconstruction, and taps its associations directly without making room for question (what we call in reading a book "suspension of disbelief" is automatic with pictures).
This is similar to the standard hypnotic technique, or story-telling practice, or magician's trick, of telling a story within a background when it is the background you wish to establish.
So it is generally easier to fool people with pictures, than with words - to convey false states of affairs. The viewer will do most of the hard work - building a plausible context, incorporating the features of the picture into their (now suitably altered) reality - for you. Instead of a linear stream of story building words each triggering the evocation of its possible contradiction, the uncontradicted claim is simply accepted as information (tell people the sky is blue, and the possibility that it might have been or maybe is or tomorrow will be orange comes into play automatically. Show a picture of a scene with a blue sky, that doesn't happen without conscious effort).
So in the picture above - the rose on the coffin, the woman with the child - a few words might be worth more. Say: "A visit to Stalin's tomb was the final step in purifying the chosen orphan for sacrifice".
