it looks like we lost an image at some point that is still supposed to display on production

is this as intended, since the semester ended? do have policy for image expiration date?

In case it's helpful, here's another one:

Ping @drdrew42 - I don't know the answer to this one.

drdrew42 commented 7 years ago

Oh, right. This escaped my prior thinking on this subject - but the course turnover between semesters is going to cause an issue regardless of the image cache flush.

Between semesters I archive the courses from the previous semester - which removes access to the course. I could keep old courses available, but this means all the old student data will persist in the SQL database. After a few semesters, this would begin to negatively impact WeBWorK's response time. I think this is another argument for archiving any images on the OpenLab side.

Thanks for the clarification, @drdrew42. See #39 - I'll be sure to prioritize that for the spring.
