XF 2.2 How to insert Image from Media Gallery in a post?


I can't see how to insert an existing image from the Media Gallery into a post? The only option seems to be to use BBcode img tags, which is clunky and difficult for less-experienced users.

I see on this board I can click the More options... drop-down, and then there is a Gallery embed icon. But I don't see that on my board. What am I missing?
