First, thanks @langlangcat for the suggestion of the Javascript. Unfortunately, that's out of the scope of what I have to work with at OSU. That being said, one of my video colleagues noted that they have used our blog site/application to host images and that this might be able to be accomplished using that. Due to the sheer number of images, it was impossible to host them in Canvas.
The process:
We uploaded images to folders named for the individual plants (image files do not contain the name of the plant) in the instructor's media library on the blog site.
We then created question banks in Canvas with the same names used in the media library.
We then created generic MC questions: What is this plant? The title of the question, of course, had the plant name and disease (this was a ton of work and many thanks went to the TAs that did the work).
Each question needed html code to direct to a specific plant image living in a folder on the blog site: <p> <img src="https://u.osu.edu/matthias.5/files/2020/11/ladysthumb-Polygonum-persicaria-32-1.jpg" /> </p>
The faculty then created quizzes with multiple attempts that included pulling a certain number of questions from each plant type he wanted in the quiz from the question banks that were created.
While this solution was not perfect with not having students get the same image twice across several attempts taking the quiz, due to the sheer number of images the instructor had for a given plant and plant disease, the odds of a student getting the same view of a plant across multiple attempts was very slim.
Proposed solution accepted by the instructor.

Got one that has stumped me... An instructor uses lots of images (plant pathology) in his lectures then also reuses the images in quiz questions. He has created several different versions of the images, typically two small blocks atop one large block, that have different viewpoints of the plant. What he wants to be able to do is have a bank of images that, when a student takes one of his weekly quizzes and needs to retake the quiz (two attempts), the student "possibly" gets a different image of the same plant when getting the same question. The instructor is not randomizing questions; just wants to randomize the images within questions. I've talked to the instructor about creating individual question banks for each plant that has the same question but each with a different view of the plant but the instructor doesn't want to go through the work of duplicating questions so that he can incorporate his 1k+ images (I don't blame him). Has anyone found a way to be able to pull a random image into a quiz question? I've seen a few posts about setting up rotating header images or image blocks within a page, but nothing for quizzes. Any help would be better than what I got!

Chris, thanks for the nudge. Mark's answer will work for the time being. The last conversation I had with the instructor was that he would like to have the quizzes automatically grade and drop the extra 2 points if someone answered all questions correctly, then do the other math automatically depending on the number of questions they answered incorrect. Seeing that this is not able to be done (feature request...), we will have to go with the fudge points options for now. He anticipates the student population for this course to explode, thus having the quizzes auto grade would be the best option.

I was also just running this through my brain with what you said about zero point questions and thought he might also be able to do all the questions as zero point then add a rubric that has number of questions answered correctly thus providing the point value he wants to enter into the grade book. Got some playing to do.

Rick, Thanks for the response. I didn't think about fudge points as I was only thinking automatic grading, which I figured there would be no way to do this (sounds like a feature request, huh?). This would be a viable option for the professor this semester as thus far he only has three students enrolled in the course. Not sure what his students numbers will be in other semesters however. Thanks!

Is there any way to drop points in a quiz similar to the way an assignment group can be set up to drop a certain number of scores? I have a situation with an instructor who wants to give quizzes worth 10 points however, there are 12 questions. Each question is worth one point. He would like to be able to allow students to miss up to two questions but still get the 10 points (100%) for the quiz. If the student misses a third question, they get nine points, etc. The caveat to this is that if a student answers all 12 questions correctly, they still only get 10 points. The extra two points for the additional two questions are dropped. There is no extra credit. Is there any way to accomplish this?

@stelpstra This is a fabulous tool you have come up with. Thanks for taking the time to answer my emails regarding adding the ability to pull email addresses in addition to names and SIS ID numbers. The code you provided should enable us to customize your original spreadsheet. Thanks! Ken
