I have tried searching for the answer to this, and I know I have seen this question a few times, but I can find the post related to what I am looking for.
I have banked all of my test/quiz questions in new quizzes in individual banks for the past couple of years. Everything worked fine last semester but all of a sudden questions do not have the pictures that I embed into them when students go to take the quiz. I can see the pictures but they cannot. I do have the banks shared with my current course and still have this issue.
Thanks for your help.
Whenever someone says "I can see the pictures but my students cannot", my first thought is that there is a problem with the image links in the test, and the image links are actually pointing copies of image files that are stored in a previous course (which you have access to, but the students in your current course do not).
You should at least try running the Link Validation tool ( https://community.canvaslms.com/t5/Instructor-Guide/How-do-I-validate-links-in-a-course/ta-p/1001 ), though I'm not 100% sure that it works with New Quizzes and item banks. It should at least tell you if it's able to spot a problem with the image link permissions.
We have had the same issue with images only appearing for some students and in some cases for no students. We have stopped using LDB because of this. Our Dean of IT says the server is fine. We store the images in files and manually re-link every picture every semester (which is ridiculous). And we use the link validation tool. But still have found this to be a problem. We have troubleshooted different browsers and have found Edge to work 100% of the time. Go figure!!
I decided to convert to new quizzes this semester and I have similar issues with the pictures. My students are using Lockdown browser. I am at a loss on how to fix this since for some students all the pictures are showing up, for some only a few are showing up and again for others no pictures are showing up.
This makes me think that it is an issue on the student end but I am not sure how to fix this problem. I have looked at the link validation and they are all good in the course. Any help would be great!
If you have converted existing quizzes to New Quizzes, and are having problems with the images showing up with LockDown Browser, I believe it's best to contact Respondus Support to see if there is a workaround.

This is what Respondus suggested to us in this same situation: "Because re-embedding all the images is quite tedious, other instructors might be interested in this workaround, which happily allowed me to bypass that unnecessary extra work:
When I grouped into a single Classic Exam the Classic Quizzes and banks that I wanted to migrate into a New Quiz bank, downloaded that exam as a QTI file, uploaded that QTI file as a New Quiz bank, and created a New Quiz based on that bank, then the images loaded correctly in Lockdown Browser."
I hope this helps,

I have been investigating this problem. I can explain why it is happening and I would call it a bug. In NQ, when you add a question to an item bank and add links or images to the question, the resulting URL points to the course in which the question was created. For example:
<p><img src="/courses/2227273/files/170623712/preview" alt="0.png" /></p>
As a result, only the students in that one course can view these items, which is very unfortunate because banks are supposed to work in any course. When new questions with links to course files are added to a bank, there's a warning about this before you save the question, but the warning is not at all helpful.
As you may recall, in Classic Quizzes, it is possible to reuse question banks in any course without this problem. The links work in classic quizzes because all files referenced in the question are copied to a hidden file store and the links are updated when the question is saved. The links for these files are not course specific and students are allowed to view them whereever the bank is used. Here's a sample link from a question in a classic question bank:
<img id="170619151" src="/assessment_questions/140076810/files/170621199/download?verifier=Wn2oXab5eNwbyrJQZY1g2M4prrsBUwb9kPLbRvaf" alt="ascending.png" />
It's not clear to me why a similar approach was not implemented in NQ Item banks. One the bright side, when legacy banks are migrated to New Quizzes, the links continue to work because they do not reference a specific course.
I am going to submit a bug report to hopefully draw more attention to this issue. At minimum, the current limitations should be documented in the Canvas Guide, How do I add content to an item bank in New Quizzes?
Just did some additional digging. The broken images seem to be a recent problem. I found examples of embedded images in questions in older banks. The URL for this images include a verifier parameter that is not present when I embed an image in a new bank question. So, I think this may be a relatively recent regression. I reported a bug and willl get back to this group when I hear back from Instructure.
I have been going crazy trying to figure out why this just recently happened. All of the images from the banks I created a few weeks ago are still working, but they have a verifier part where the others don't.
\<p> <img src="/courses/148714/files/9732986/preview?verifier=yVV4FkXvKTmJYaoXyfKTrciQYwtW6Y8DF8fCuuQ4" alt="image.png" /></p>
Things without the verifier part don't work. I've run the link verification tool, and it doesn't fix the problem. Did Canvas update recently?
This is an issue for my institution as well. It is not an issue for all courses, however, and as @leward pointed-out, it seems to be a recent problem.
I too see that some images have a verifier parameter, these are the images that work. However, now when uploading an image, or using a course image in an Item Bank question, there is no verifier parameter.
This is a very frustrating issue. Images in Item Banks should not be associated with a course, they should be able to be used in any course. One of the workarounds is to link to images from a public course or website, but surely Canvas can make this work without a workaround.
Hi,
I reported the issue to Respondus Support and they got back to me with a workaround that appears to be working for us.
Upload your images to your own User Files area and then embed them from there. It worked when I tested it.
Thanks!

Yes, uploading to Personal Files does work, but it's not the default workflow for the Canvas RCE, it requires more steps than just uploading images while authoring questions, and faculty who are unaware of this bug will continue uploading to course Files without realizing the links and images won't work in other classes. Hopefully, Instructure will acknowledge and fix this bug very quickly.
Here is what Respondus said:
Hello Jane,
Thank you for contacting Respondus Support.
This is a known issue that we reported to Canvas. You'll want to contact Canvas Support to inquire as to a timeline on their fix. You can reference Canvas Case 10188336 when you email them.
It seems to occur when a classic quiz is migrated to "new quizzes" format. But a similar issue can also occur for a brand new "new quizzes" exam, depending on how the image was embedded and what file space the image resides in.
Until Canvas can provide a long term fix for this bug, they have supplied the following workaround:
1) Upload the images first to the user's user file space (not the course file space.) I presume they mean the instructor's user file space.
2) Then, embed the images into the question from that user file space (not the course file space.)
3) After doing this, the images should display when using LockDown Browser.
In our testing, this method does work, displaying the images successfully both for a brand new "new quizzes" exam, as well as a "classic" exam that has been migrated into "new quizzes" format.
Regards,
Bob

We are having the issue with images not displaying when using Respondus Lockdown browser. I contacted Respondus support and they emailed back:

Our teachers are not very happy having to use the workaround as they use a lot of images in the quizzes and all the extra steps.
This is not possible when the New Quiz is in a Blueprint course used by several teachers and all questions are in item banks.
I was wondering about this. I don't use the blueprint course, but I created item banks and shared them with my colleagues who teach the same course. If I change the pictures so they are connected to MY user images, won't my colleagues still have the same issue? (e.g. New Quizzes not being able to access the image?)
If you place the bank images in My Files, they should be visible to Canvas users in any course as long as they have the "Only available with link" permission.
Also, at this point, as long as you replace broken images with ones stored in My Files or Course files, the fix deployed in June of 2024 should make the image available to students in any course.
Does anyone have an update on this? Giving an exam this week and my last exam, pictures didn't show up!
Thank you,
Jane
@JaneWilliams
Instructure has confirmed that this is a bug, but has provided no indication as to when they expect it to be fixed.
If you are using your banks this week, you may want to use the suggested workaround of uploading the image to your personal files rather than course Files.
Hi,
Thank you for your quick response. When I gave my exam last week, older pictures showed up and these files are in the course in an Item Bank. Going forward, do you know if the older photos that came with the course migration will show up in the future New Quiz? Curious of what is the difference. Also, I'm using Respondus.
Thank you,
Jane
@JaneWilliams
When I last tested, images in migrated quizzes and banks were working. The only images that were not working were those added to banks after this bug started occurring some time in mid Feb or early March.
If you enter student view and take the quiz, you should see what students see and do not see.
Hi,
I checked my exam from student view and preview before the exam and the pictures were there. However, I will check this out again before our next exam as I'd like to populate new pictures and hot spot questions with pictures.
Thank you,
Jane
Hello,
Is there any updates on this problem?
Jane
Not at this point.
Cheers,
Dana
Our CSM is tracking this bug. No news as of yet. I have prepared the following documentation about it for our faculty. Feel free to all or parts of it, if you find it useful:
https://docs.google.com/document/d/1mk9yk2IArSYoysDJLq-QO0mKtDUVl2u0a1DATVNV6Is/edit
Thank you for compiling this page. I am going to share it with my fellow faculty resource specialists. 🙂
Yes, thank you! I put a ticket in with Respondus today for an update and will let you all know if I learn anything. The work around is cumbersome but glad you figured it out and made this wonderful doc!
Jane
Hello, @NatalieGamble. Yes, this does seem to work. It's unfortunate that the files are not automatically set to public when the image is uploaded to a bank question. But it's definitely easier than uploading the images to user files and redoing the links.
Interesting. I tried the same solution, setting visibility to public, and it did not seem to work for me. But this was also a few weeks ago when the problem was newer. You never do quite know what Instructure is changing behind the scenes.
I ended up having to go into the item bank editor, download the images, and reupload them into the questions.
I hope this bug gets fixed soon!
@pjonas1 . My first attempt failed too. Then I realized the the course I was using for my test was not published. Once I published the course, the images were visible by students in other courses.
This was for a set of currently active winter courses. This lovely bug threw a grenade into my courses during midterms. 🙂
I'd love to try that but I can't even figure out where the image is stored! The source code is "src="/courses/1496617/files/66613095/preview" alt="" but when I try and figure out where that file is located even with search it isn't working. This is a very frustrating problem!
Oughf! I work with instructors who had the same experience in their fall courses. Sorry to hear you got to live it too @pjonas1. 🤕
Instructure has finally owned up to this problem publicly in the New Quizzes End of Quarter Update for Q1 2024 (see the section Q2 2024 Objectives) and I have posted a very lengthy reply. If this bug has been a major painpoint for your or your institutions, please consider adding a comment to this post.
Our CSM let us know a hotfix was applied to our system on May 1, 2024 that addressed our specific use case: NQ images pulled from item banks did not appear to students using Respondus LockDown Browser. Curious to hear if this fix addressed other use cases with NQ and images.
Nope. The verifier is still missing and students in other classes still can't see the images.
I tried sharing Item Bank with a different course, also all images are broken. How do I share a item bank so that the images work?
