The Webcam Network is a network of webcam/image publishers and subscribers. Users can publish to the network using the publisher tool and subscribe to the network using the viewer tool. The publisher tool will push images to the network at an arbitrary rate, and the viewer will display image updates from selected publishers in real-time with resizing, scaling, or in collage mode. The viewer can also render to the root window.
