Add demo images to module homepage

I've been watching the module for a while and have even asked a few questions for different use cases over the past few years. That said, I still haven't had the time to actually test install and try it out... but I will! But, I was also thinking that some example images of some general use cases on the module page would be very easy references to help myself and others quickly determine the module's capabilities and how it may be incorporated into other sites.
