Hi, I thought it was a Javascript implementation of the Silverlight DeepZoom code, but I'm not sure either. The IIPImage server supports various protocols and clients. From a jpeg2000 or pyramidal tiff it can stream tiles conforming to DeepZoom, Internet Image Protocol (IIP) and Zoomify protocols. This allows it to work with lots of clients including IIPMooviewer, OpenSeaDragon/SeadragonAjax, Zoomify, OpenZoom, OpenLayers, PanoJS, JIIPImage (and maybe Silverlight, I'm not sure). There are demos on the IIPImage site [1] and some more on the Old Maps Online site [2]. Coming at it from the client-side, the IIPMooviewer 2.0 beta can display tiles from any of the IIPImage Server protocols, but it can also load pre-generated DeepZoom/OpenSeadragon/DZI or Zoomify tiles without the need for an image server.
