Image availability with the repository

[nav9]

Hi. This is a very minor issue, but I hope it could be addressed. The block diagram you've provided, which visualizes the various components, is located on github usercontent. So when we clone or download the project, we don't get to see the image locally. It would be nice if the image was shifted to and referenced from a "gallery" folder within the project itself, so that it'd be available locally.
