The digital project La Grande Collecte [The Great Collect] was an initiative in 2013 and 2014 launched by the Bibliothèque nationale de France, the Archives de France and the Mission Centenaire 1914-1918. In this crowdsourcing project the aim was inviting the general public to bring sources from their private collections to the regional archives in order to digitize and publish them on a separate online platform. You can use the free text search field to search the results at will, use an advanced search mode (Recherche avancée) or filter them by the type of document (official publications, correspondance, diaries, photographs and drawings). In its present state this digital collections contains for these categories only a few dozen examples; there are some 130 photographs. The collection can only be accessed in French.
