The visual communication process involves the production, transmission, and receipt of messages through images. It includes key elements like the context, sender, message, receptor, code or language, and channel or medium. An image functions as the main vehicle for visual communication, transmitting information through its signifier (visual content) and signified (intended meaning). The meaning of an image depends on the context and is open to interpretation based on one's perceptions. Visual language serves informative, exhortative, expressive, and aesthetic functions depending on the message an image aims to convey. Pictograms are simplified symbolic images that convey meaning through basic shapes and forms.
