Wide images are resized to the width of the column so there is a feature to display them at their original size by hovering over the image and clicking on it. The screenshot below shows what I see I hover over an image:
This issues becomes worse in the Editor Preview pane which is less than half the screen width. I can’t see any way to preview the image full size. This means that I have to view the image in another application.
I’d be happy with a preview pane that can be the width of the browser window.
