The feature to attach an image does not appear to work. A 20-second screen recording shows how nothing happens, and this is from a super administrator's login: https://screencast-o-matic.com/watch/cYX20vM8WJ
I was not able to test this out on the Compojoom demo because of lack of permissions. But in this case, nothing appears at all to the user.
Is this supposed to work? If so, what's wrong? I haven't been able to find anything int the documentation regarding this.
