OpenSeadragon

OpenSeadragon is an image viewer that can adapt to any of your projects.

By default it includes support for image zooming, drag-and-drop panning, auto-centering, and various buttons for controlling the widget. All of these can be turned on or off, based on each project's requirements.

Other cool features included are keyboard shortcuts, support for image rotation, highlighting special image areas, image tooltips, overlays, and a debug mode.

Besides single images, developers can show multiple images to create a full-blown image gallery, and even OSM or Google Maps.

Demos and docs are included with the download package.
