When I create a new quiz with images in the item bank, it looks great to me.  All the pictures are there all the answers are there so I share to my course.  When a student opens the quiz the image is broken and will not work.  The questions and text are still there, but the image disappears.  So I go in and try to fix within the course.  The image appears for me but not for the student.  This also seems to happen when I import the item bank into a different course to make a different quiz.  It appears in the bank for me, but when the student opens it up the image will not display.  

How do I fix this?
