Ridged Body World and physics animations - Addons and Rendering and Materials

I noticed that this add on was in the sensei format. See attached:



I am wanting to know if I can download an addon that is shown here ? without having my whole world in Blender changed by using the sensei format.

I also am having conflict about cycles - I want to animate jpg images on boxes. Will blender render or game render render with jpg as materials. ? I think I read that you cant animate physics and render with cycles. I want to apply a photos to boxes and animate them with the physics animation. Display and show pictures in quality. Will blender render or game render do this for me ?

Much appreciated thanks
