I am consistently having this issue. I will assign a quiz and the image associated with the question will not appear when the students are taking the quiz. Instead a white box will show up. I have had to print the test repeatedly.
Some background info:

Hi, It's hard to know without being able to look. Definitely this can happen with copied courses. So it's good you made sure the images are in course files, and I'm guessing you re-embedded them in the quiz questions.
Some things to try: Ask your students to try on Chrome. And maybe have them clear the cache.
Does Safari vs. Chrome matter if they are using the LockDown Browser? I did re-embed the images. I tried to work with Canvas Support and they also could not solve the issue. It is now occurring in my now un-copied classes.
