Test Bank images not showing up

Using a test bank. Gave a quiz once and worked fine. Gave a second quiz and now none of the images are showing up in the student's screens. Works on my computer (the originating machine), but not on anyone else's. Not sure how to trouble shoot as my computer has no problems.

I had the same issue.  I am using Examview software and exporting to a Blackboard 7.0-9.1 zip file, which is then imported in to my Canvas course.

I discovered that images would not display correctly if I edited a question AFTER the students had starting taking the exam.  I looked at the HTML code and discovered that Canvas alters the file path after a question has been edited.  

Here is one of my question images:


Here is an example of the HTML code BEFORE editing a question:

<p>Use the map below to answer the following question<br /><br /><img src="" alt="mc033-1.jpg" width="425" height="360" align="bottom" /><br /><br />Based on the Supreme Court case of Shaw v. Reno, a possible justification for the above congressional district boundaries would be that</p>

Here is the HTML code for the same question AFTER editing the question

<p>Use the map below to answer the following question<br /><br /><img src="/assessment_questions/4733421/files/6911282/download?" alt="mc033-1.jpg" width="425" height="360" align="bottom" /><br /><br />Based on the Supreme Court case of Shaw v. Reno, a possible justification for the above congressional district boundaries would be that</p>

Here is the broken image


This problem seems to be related to the 'Preview mode" of canvas.  Changes work for the person editing the quiz, because they are seeing the changes reflected in the preview mode, but students cannot see the image because the file path of the image has been altered. I even tried copying the original HTML code (you have to do this with the HTML editor) and pasting it back in, but whenever I click on 'Update question' - it reverts back to the modified HTML code shown above in red.

The workaround I am using is to make all quiz corrections in ExamView and then re-import to canvas. I then assigned the corrected version only to classes that had yet to take the exam.  ANY edits to a question containing an image produce the same result.#broken images

Just to add to the record in hopes that someone will look into it--- I had the same problem for my first exam last week and had to drop 7 questions from the test. Same problem as described above, i.e., images showed up on both of my computers, but for none of the students. Two differences: 1) we do not use ExamView, and 2) the images also showed up when I was logged in through a fake student account, as long as I was on one of the two computers; they did NOT show up when I logged in through my phone. Oddly, all the images were showing up for everyone by the afternoon. I do not remember this happening until this semester. I assumed that something was broken between Canvas and AWS.

Hello Lawrence, 

I have encountered similar problems with embedded images in the past. One thing to check is that all of your links are pointing to content that is actually in your course, if you have imported these test bank questions from previous sessions of your course. This would make the image show up fine for you and any troubleshooting admin (because you both have access to the previous course), but would give errors in student view and to students, because they, presumably, do not. 

I hope you have been able to iron out the display problems since I see this Q is a little old!

Excellent thread here. Thank you so much, James Stone, for capture the issue so completely.

That is exactly what I am noticing. Even down to the HTML code... and noticing the "download?" mode versus "preview".

Is Instructure chiming in on this anywhere? We have one use case that involves 1400 students, and hundreds of questions scattered across an amazing array of question banks. And, we've been having spotty stability last semester and this semester.

Is there a "fix"? A "best practice"? Some way to prevent this from happening?

If that last comment (from Thomas Pile) is correct... that can be a serious problem and needs to be aired out:

Is it possible to create a quiz question, and insert an image that I can see (as an instructor)... but my students can't?

I would reallllly like to see a rationale for allowing that. What is the point of Canvas accessing a file-storage space that students can't see?

Yes... I'll be escalating this to the support team.


We have several cases in on this issue.   Different things will work at different times.   Clearing cache and cookies will sometimes work.  We have never gotten a good answer.   Also have found that if I am working in Chrome but the students use Firefox, that usually works.  We have too many schools and students for any of the temporary fixes to be a good answer for us.  We would love to see this one fixed.

We've had this same problem happening in our school. It would be good if we had someone from Canvas Support to tell us what to do.

 @lmoreira , have you had each affected user submit a ticket about this to Canvas Support? Each of these issues needs to be evaluated individually and in their context by a member of the support team.

stefaniesanders‌, I'm not sure if we can directly contact Canvas Support in our school. I'll check here and will probably ask for your guys' help.

Thank you!
