Right now the only way to include an image is to upload to a server and post an url. The problem is that this now relies on multiple servers and the images are not associated with the course. Much better to be able to create a locked folder in Files and link directly to those images. It appears that we can do this is in the Quiz but not in the Question Bank -- the problem is it is necessary to use the Question Bank to randomize the order of questions and for mananging quizes in general.
