So, isn't that the culprit?

,----[ C-h v mm-inline-text-html-with-images RET ]

I would try setting that to t and use shr as the renderer.

I've set it to nil (because I've also discouraged text/html display, and
thus actively have to choose to show HTML-parts).

Are the images in your emails inline or linked?

We don't know that my setup shows the images, as you haven't provided
anything to test on.
