A presentation device includes an embedded web server for transmitting images representative of presentation information to network-connected terminals concurrently with the display of such presentation information at the presentation site. The images may be viewed at the terminals by pointing a conventional web browser to a DNS name or IP address associated with the presentation device. Certain of the terminals may be given presenter privileges, wherein the users of the presenter terminals may control aspects of the presentation such as slide sequencing by engaging the appropriate controls displayed within the browser window. In this manner, presentations may be viewed and controlled remotely using a conventional browser interface.
