Finally found the bug and a very easy fix. All references to addslashes should be removed from file questionnaire.class.php.
Fixed in versions 2.4 and 2.5 of Questionnaire, and committed to the github. CONTRIB-4706.
Thanks to Barbara for reporting this problem!

Hi
I have the same problem. I inserted images in some of the questions and they do not show anymore. (The question types differ, so it is not only for the rate type questions.
I upgraded the past weekend from Moodle 2.8 to Moodle 3.1.
They showed before the upgrade, but they are gone now. When I go to edit, the image displays, but when I preview the question, it does not display.
I also changed the theme from BCU to Adaptable. (not sure if it is relevant)
Hi -
I will take a look at this and see if I can find the problem.
