Is there a difference between content selector for images and image insertion in the rich text editor?

Jump to solution

When working in the Rich Text Editor, I see 2 methods of adding an image, the content selector and the image insertion icon.

Using the content selector, images tab, I get something that looks like this in the HTML view:

<img src="https://canvas.wisc.edu/files/3796091/download?download_frd=1" alt="badger1.PNG" />

When using the image insertion icon in the menu, I get this instead:

<img src="/courses/39014/files/3796091/preview" alt="badger1.PNG" width="339" height="313" />

Is there a difference between the two?

An instructor I work with had a problem with images not displaying (which I thought had been fixed in the 02-03-2018 release). I'm wondering if it could have anything to do with how the image was added to the quiz. He was using the image insertion icon.

Thanks for any insight.

Hi  @kona ,

Thanks for the reply! That's a big difference. I hadn't noticed that the image insertion icon gives the option to pull from personal files. It does also have the course files option. We have a ton of instructors who rotate teaching courses, so I could see this being a potential problem.

I did a test just now. I uploaded an image to a test account's personal files, then added the image to a page using the image insertion icon. I then exported the course and imported it into another course on a different production server. Then I deleted the original file from the test account's personal files. That broke the image in the original course and in the imported course (although it did take about 10 minutes for it to break in the imported course, lulling me into a false sense of security). 

I feel like a warning message ought to appear when adding personal files to a course. Or maybe that option shouldn't even be there? Minimally, add to list of best practices: use only the content selector for adding files or images to a page.

 @skhagen , Sorry your question has sat here unanswered for so long! Were you ever able to find an answer to your question? 

From my understanding using the Content selector adds the image file to the course. So when things get copied over from one course to the next The image file stays with the course. This is the way we recommend that faculty add images to their Canvas course. 

The image insertion icon adds the image file to a persons personal files in Canvas, not to the course files. It is a link from personal files to that place in the course. In theory, I would think that as long as it’s the same Instructor they should be able to copy their content from one course to another and the link to the image file should be ok. Yet, if you’re having problems with it, then maybe not. 

Hope this helps!
