Abstract : The aim of this article is to identify the different uses of images by secondary school pupils in their information-seeking activities. Empirical studies have shown the use of images in the process of information seeking and information evaluation by novices. Our study reveals a more diverse array of functions. Images can be a strategy of quick access to information considered relevant, through the use of Google image in a way which was not antici-pated by its creators. Images can also become a negative selection criterion, sufficient to rule out a piece of informa-tion. Images also play a part in the accumulation of knowledge about an unknown topic. During the phase of infor-mation gathering, images can help express an information need.
