At the beginning of the 20th century, pictures only played a marginal role in the devices aiming at seducing and informing the readers of the daily press. Forty years later, they were highlighted by being displayed on front pages ; they were the subject of many discourses both inside and outside the editorial offices, playing a part in their methods of dealing with the news. Between these two chronological landmarks, daily papers, a medium often originally designed for written material, took over pictorial material as well. Taking the example of Le Journal, a daily paper founded in 1892 and discontinued in 1944, this dissertation aims at reconstructing the history of this appropriation which was a multi-dimensional process strongly determined by the editorial strategies of this major leader of the daily press and the economical & technical constraints that it had to comply with. Analysing the discourses, practices and uses dealing with pictures makes it possible to show the evolution of the different forms of photography during that period, the interplay of media visual culture in the Belle Epoque and the interwar period in order to have a better understanding of how the news was represented by images.
