@kriskorn Thanks for the report - I see the problem too. I'll have a look at it this week 👍
But please host the images on GitHub directly, so that everyone can see them :) (and won't get deleted when/if that site gets deleted/removed/etc.)

@klimeryk Thank you very much for the tips. All should be good now. I have replaced the images and added some clarifying steps.
