An open-source, web-based viewer for high-resolution zoomable images, implemented in pure JavaScript, for desktop and mobile.
OpenSeadragon supports several image serving protocols out of the box and is actively adding support for more. If the image serving protocol you need is not supported, you can always add support for yours using a custom tile source. (Please help us add built-in support for your required image serving protocol.) Each supported protocol aims to allow configuration via XMLHTTPRequest, JSONP, as well as direct inline configuration.
