When contemplating a location (directory path) for image files, consider that there are two worlds (Heroku & GitHub Pages) with differing requirements.
Any images referenced in demo and tutorial sessions should be located in "public":
odop/client/public/designtypes/xxx/imagename
Any images in Help (GitHub Pages) should be located in a "docs": subdirectory:
odop/client/docs/Help/images/imagename
See issues #243 & #244.
