This paper presents a data model for images immersed in the world wide web and that derive their meaning from visual similarity, from the connection with the text of the pages that contain them, and from the link structure of the web. I will model images on the web as a graph whose nodes are either text documents or images, and whose edges are links, labeled with measures of relevance of one document towards the other. The paper presents briefly the features used to characterize the text and the visual aspect of the images, and then goes on to present a data algebra suitable to navigate and query the database.
