Content creation

I want a functionality to allow users to hover over a word within a Course Presentation and it will display a short definition.  The Drupal Definitions Module claims to do this but this will not work within H5P content.  Is there a way to do this?

Rather than having to upload images, is it possible to display them directly by referencing the web address.

We will be using open access images (and video later) from the collections in commons.wikimedia.org and the Flickr libraries with Creative Commons licenses.

How do I get a score at the end of my interactive video?
