Do Visuals Always Work Well?

Bolter’s writing is quite intriguing. I am quite interested in discussing the code and the interpretation of writing. The author might have his secret code when composing, but the interpretation is totally at the hand of the readers. When the author is composing, he might want to express his thoughts, or to inform people, or even to formulate an argument. The awareness of the audience probably helps the author to choose how to compose and help the readers to decode. This week’s readings reminds of the feminist readings for introduction to composition. We can be confined as well as inspired by our life experiences. Such experiences can determine the way we want to compose and decode. When I walked on this campus, I could not understand at least 80% of the posters. Usually we may assume that visuals help readers to understand but it is not always true. If the poster is text-heavy, I tend to understand it better compared with those that have more images. I do not know who those people in the posters are even if they are BIG people and what some of images symbolize. Therefore I cannot decode what the designer wants his audiences to get. It is easy to spot visuals in the modern world and people tend to rely on them but to read beyond these images is difficult. It is a painful experience but at least it shows visuals do not really work well everywhere anywhere.
Do you understand what the image on the left suggests?
