I would highly recommend staying away from the images. I would prefer just a bulleted list of the topic as a hyperlink. It is a much cleaner look and much easier to see what all of the lessons are about.

 

Pictures only as a second option please.

Sounds very good, the documentation is one of the most important things.

I prefer for tutorials .html .chm or .pdf files a lot more than videos.

 

For new implementations my suggestions are: A fileformat that is used e.g. inside Blender or an other free modeler for import (export is also nice).

Used to making Modder-Games, people which have only the game and not Leadwerks itself can create their own models for such a game.
