Hi Alan, Glad you like the example.
Three things: 1. It still works for me ;-) 2. The distorted png might come from the bug in htlatex I mentioned in this thread [1]. 3. It seems that the by-backend does not work properly for you. I am not sure about the reason for that. What org-mode version do you run?
