Instructors and designers can add images to any text box in Moodle, including in:
Descriptions for Assignments or Quizzes
Note: Do not add images that have a large file size to text boxes that display on a course homepage. These images must load every time a student returns to the course homepage, slowing down the display of the course homepage.

Add alternative text for the image for accessibility in screen readers:
