What JQuery Plugin is being used here?

Question

I found this brilliant image map plugin on the BBC here: http://www.bbc.co.uk/news/uk-18295433

The highlighted links are essentially normal tags which have had their position set to absolute to hover them in different places on the image. Then they are using a javascript plugin file to zoom into areas on the image depending on which tag is clicked. The javascript plugin file is here: http://node1.bbcimg.co.uk/glow/glow/map.1.7.7.js

However I can't find an open source version anywhere. Does anyone know of anything similar or what this plugin is actually called?

Answer 1

This is using Microsoft's Deep Zoom - Seadragon Ajax.

The SeaDragon component also comes with ASP.NET Ajax Control Toolkit.

It's currently licensed under an open-source compatible BSD license.
