Wikipedia is one of the world’s most widely used sources of information. By using the encyclopaedia, people form an understanding of the world. Nevertheless, most people know very little about how it works – and those who write rarely bring up their thoughts on images and image building. Images play a big role in how we perceive a subject – does the image of a suburb show neat greenery in July or a dingy street in November? Understanding this is an important educational mission and matters to our society.
