@JohnLeland you are in safe hands with @dbrace and @Chris_Hofer
I would add two pennies worth
1. Our home grown assessment solution means that our Canvas Assignments are no longer visible to Instructors when using the 'View as Student' button, which is somewhat inconvenient and generates a lot of instructor support calls
2. It would be worth checking with your local Canvas support as to whether they can set up a test student account which would allow you to log in and experience your course as a student using an incognito browser
You might also try adding student to your own Course enrolment in People (if your local settings permit this) which may allow you to see the images.
- Do make sure that you take this off again as soon as you are done as it can have unwanted/unexpected consequences for your permissions
