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.
