Broken images were on my end. Please clear your browser cache if this problem exists for you. If the problem still exists after the cage clear, please let me know.
It works for me too, but I think I've found another issue.
Didn't added pictures use to be clickable before?
If I remember correctly they were added, in the text, in a smaller size, and when I clicked on it, it was opened in a new tab.
Now, all pictures are added in the text in full size.
