Right, that's easy however rather than http:// I need file:// to work.
Also note this is visually the intended result which can be achieved however the image itself is served from the provided http source.
In my use case it's intended the http source go away. I have at a OS file system level the contents of the old http source of the images. I would like to use file:// so that nodebb 'owns' the source files rather than just have content of http hyperlink
PS. that's a darn good looking burger.
