The Visualisation and Images are the entities with which all thinking is considered to take place. Hence they are central to the process of learning and consequently to that of teaching. So, the role of visual images in intensive lectures will be introduced. In this essay, I consider how they can facilitate how chemistry students understand and learn through molecular visualisation. Indeed, I will present the role of visual representation in science communication. The extensive demand for effective scientific visualisation alongside rising sensitivity to popular considerations has created a reckless culture of image manipulation. Scientists, artists and illustrators take a wide licence as to how they manipulate images for their purposes, but a minority of viewers is conscious of or alerted to what has been changed.
