Haha, yes (probably safer w/your images) and no (not helpful - but thanks for the comment anyway😊).
This is indeed not my day job, I’m just running these fora “because I’m the one who could do it” as a pilot program so we can convince our IT department to pick it up and run it for the entire University of Oslo.
Fortunately, that seems to have worked, so hopefully this is the last semester that I have to run the show. I bet the IT department will use the images… 
And thanks, @Falco, for pointing out that there is a Ruby version mismatch, will have a look at it if/when I run into problems with future updates.
