Outdoor advertising has dominated the visual landscape of cities around the world. Outdoor advertising in city streets and public places are different than the ones located in other places for many reasons. First, it is directed towards particular audience who has no option but to look at it. The research problem lies in the excessive use of images in ways that may have been randomly put without taking into consideration certain factors such as allocation, processing, design construction or some expressive and psychological aspects. Experts have defined some technical problems related to image-choice and the extent of its future impact as a communicative force that affects viewers’ or consumers’ decisions based on outdoor advertising. The goal of the research is to identify the role of images used in outdoor advertising designs and their impact in attracting the viewer’s attention and in the same time to deliver the right message.
