General discussion

For technical training purposes you can make quite easy "animations" by just making a "multi layer presentation" of more than than one image. This can be used for such things like showing "different states" of technical equiment.

As an excample, I have made one Flash animation/presentation that shows two states of an elecrical relay here:

In a presentation like this:

http://h5p.org/tutorial-course-presentation

http://h5p.org/node/736

.. can the graphical elements only be of the type .jpg .png and .gif or is it possible to use some kind of vector based format?

(So that you can do full screen good looking presentations using only a small file size.)

The presentation module should be should be a bit more "useable" if the two arrows were used for "last slide" and "next slide".

I guess this modification should require just a minor modification of a java script that is hidden somewhere in the h5p module and that controls the interactivity of the module (When module interactivity is used by end-user.)

Is this right or will there be more "reprogramming" to do?
