Define
An image is dropped into the column of type so the reader meets picture and argument in one scan.
Mechanism
In-flow exhibit. The figure is not a separate see fig. 2. It starts the paragraph. Eye and mind start together.
Verdict
Long copy must show as well as tell: a product cutaway, a before/after, a map in the story.
Don't
The image is stock garnish. If it can be deleted without changing the argument, it is not an exhibit.
