I see. I initially thought the url changed when you uploaded a new image (with the same filename), since I saw a plugin do that for one of their images.
But upon further investigation I can see that this is not true for course images.
Wouldn't it be better if the url changed (timestamp) every time a new image (with the same name) was uploaded to moodle, just like js and css gets a timestamp in their url?
But as of now I will go with your suggestion of extending cache on a CDN level.
