z929669 testing image posting from Copy link:
Works fine for me, so it must work for everyone else that is doing it correctly:
On Copy (or whatever provider you use), right click on your image asset, select 'share', then copy/paste the link into the image dialog you see when clicking on the little picture icon in the middle of the second row of the post editor:
EDIT: It turns out that we had defined several basic extensions as valid for posting images, and even after including a 'null' extension, I was not able to post an image as this test user. I went in and removed those restrictions, and it works now :/
