Visual communication takes place through pictures, graphs and charts, as well as through signs, signals and symbols. It may be used either independently or as an adjunct to the other methods.
Symbolization is an important definition for this perspective. Cultural perspective involves identity of symbols. The uses of words that are related with the image, the use of heroes in the image, etc. are the symbolization of the image.
The view of images in the critical perspective is when the viewers criticise the images, but the critics have been made in interests of the society, although an individual makes the critics.
