To add a plugin, include the plugin script in your page head and register the plugin through the Annotorious JavaScript API. Example:

  <!-- Import main Annotorious script and CSS -->
  <link rel="stylesheet" href="css/annotorious.css" type="text/css" />
  <script src="js/annotorious.min.js"></script>

  <!-- Import the plugin script -->
  <script src="js/example-plugin.js"></script>
  <!-- Use the API to attach and activate the plugin -->
    anno.addPlugin('ExamplePlugin', {});

Storage Plugins

Storage plugins connect Annotorious to different types of databases or storage backends. You don't necessarily need a storage plugin to persist your annotations - you could just as well roll your own solution using the JavaScript API - but storage plugins may make your life easier. Storage
