I'm not sure this will work for the README and PyPI. You could try making a preview release based on this branch to see whether the images are shown correctly on PyPI.

The alternative is to include the full path to the image (the full https://...) rather than the relative path which is treated differently on GitHub vs on PyPI.

Interestingly, the HTML specification <img ... width="100"> did not work in the documentation. However, I circumvented the issue by reducing the size of the images.
