As part of the research project « Art urbain, art public et cultures numériques : des publics, des sites, des trajets », we study the public’s concrete actions on art, observing the circulation of artwork photographs online and the resulting gestures of enthusiasts. Our observations begin with the publication of artwork photographs on Flickr, which allows us to analyze the visibility of the images and encourage their reuse, to then trace how these photographs are reproduced elsewhere with a tool that automates the search by Google Image. The images are found on various websites that we then geolocate in order to map them. In this article, we investigate the online lives of photographs of Nancy Holt, Walter de Maria and Robert Smithson’s land art pieces. Between the fixity of works anchored in the landscape, the mobility of online photographs and the movements of traveling publics who in turn publish on Instagram, we are witnessing a becoming-destination of these works. The use of digital tools and theorizations allows us to renew our thinking on art’s circular logics of production, propagation and validation.
