Some common misconceptions of 'Image' in the context of this module are:
Image = Imagery
Image = Body Image
Image = Pictures
However by definition in this module:
Image is NOT imagery
Image is NOT body image
Image is NOT just pictures
Image is experience through visual language. In other words, it is our interpretation of an external representation of a person or figure. For example, a person may be into punk rock culture and may externally present themselves in this way (e.g. black messy hair, body piercings, rude, listens to rock music with screaming vocals etc). We may view/interpret this person as uneducated, irresponsible and criminal. This is the image of this person to us. Whether this image is true or not is a different story, but for the sake of this module, composers use many language devices to project an impression of a person (e.g. the hero and the villain of a story). This impression is called the 'Image'.
Stereotypes are good examples for articulating the concept of Image.
