Imagery is the picture-making that words — or a film’s shots — do in your head. In a poem or a story, a writer chooses sights, sounds, smells, and feelings so you do not only understand the idea; you almost see it. Teachers often ask, “What imagery does the writer use?” and they mean those picture-details, not photographs glued into the book. In film, people also say imagery for the way the pictures themselves carry meaning: dark streets, a repeated colour, a quiet empty room. Though actually, outside school some people use imagery more loosely to mean “the pictures” or “the look of the campaign”. The school meaning is the craft of making meaning through pictures, in language or on a screen.
