What do images in literary works mean?

Something with certain significance and emotional appeal, which is a fusion of objective image and subjective mind. An image is a smaller unit than a drawing, and usually consists of words that describe the object, such as details, symbols and puns. It has a wide meaning, and there are four main types: 1. Psychological image. It represents the representation or memory of past sensory experience in the brain, and the perceptual image presented in the brain only on the basis of perception. 2. Internal image. A brand-new advanced image designed by human beings for a certain purpose. 3. Generalize the image. It is the general name of all artistic images or linguistic images appearing in literary works, which is basically equivalent to artistic images.
