In IE11, I can get the URL of an image on a page

Why cannot this be done with edge, or is there a
work-around?

It's possible to copy an image URL, but in the
year 2018, not all images or even text, are left open
for access. A web designer can lock them down, or
lock them down for someone using Adblock, and not
lock them down for an open browser.

I know you've done an apples to apples comparison, so it
could be that some subsystem is missing from MSEdge to "please"
the web site code enough to make access available to you.

But at least, there is a menu item to do it. It's there.
There's a "Copy Link" as well as an "Open in new windows"
for the image URL.
