Abstract: An image store including images from photo agencies is established by an image management system. Marketers interact with the image management system to review images in the image store and tag objects shown in the images. The object tags identify and provide information about the objects shown in the images. The marketers define campaigns having payment conditions indicating types of engagement with the images that trigger payments by the marketers. Publishers interact with the image management system to select images and publish the selected images to clients used by consumers. The publishers also provide the consumers with tag modules that execute on the clients to display the information about the objects shown in the published images. Consumer interactions with the displayed information are reported to the image management system, and the system accounts for payments by the marketers if the payment conditions are satisfied.

Abstract: The system and a computer-implemented method annotate a multimedia object on a web page hosted on a publisher computer system. A web page that includes a multimedia object is rendered in a web browser of a client computer system. One or more layers, including a transparent layer, at least partially located over the multimedia object displayed on the web page are generated wherein the one or more layers are configured to facilitate the creation and display of annotation data for the multimedia object based on user interface events produced by a user of the client computer system. Annotation data for the multimedia object is received from the user. The annotation data is transmitted to an annotation server for storage. A visual indicator indicating that the annotation data is associated with the multimedia object is displayed, wherein the visual indicator is rendered in the one or more layers.
