I have a round of quiz questions where the question is an image with a typed answer. For this I am picking the single line text answer and am putting the image in the description rte.

The RTE doesn't select images from Joomla, and I am having to get an external link. The image shows on the backend, but is not being shown when the quiz is run.

The link for the images gives even not found or 403 error.

Is there a better way of doing picture questions, and/or what am I doing wrong with inserting the image?
