I vote against images in CS, simply because of the “purity” of the form - a world of pure imagination. I instinctively react against messing with that form.
But pics can be enjoyed in their own right too, and can even add to a story (eg in “Divided We Fall” the pics are beautiful, and give a sense of history - since they are photos from the real-life historical setting). And of course a lot of games have such gorgeous imagery that it’s like walking through a gallery as you read.
And I’m utterly opposed to NJG’s view* that a person might imagine something “incorrectly”. That’s precisely what makes imagination better than pictures. As long as the basics agree (which is only really anything plot-relevant eg if the character’s hair is pulled later, we need to know they have long hair when we first meet them), a reader can add wonderful layers of meaning and depth that are special to them, improving the story.
An example of imagination getting it both right and wrong…
The actor who played Samwise Gamgee in the Hobbit movies said that Christopher Lee (massive Tolkien fan) had made sure he grabbed Frodo’s hand when he awoke from illness. It was in the book. To Tolkien, it was probably a minor thing, but it meant a great deal to many gay men. They’re probably imagining something Tolkien didn’t consciously intend, and that just adds depth to the story.
