jsmol image broken

[xiangjf]

The image files Al2O3.png and 1hxw.png under static/jsmol broken, leading to the failure when import course.

When I import course I also encountered such a problem

This issue is 10 years old now :)

The original demoX course has been replaced the jsmol problem is no longer a component in the course.
