I'd be a bit more direct. Something like "Outline cycling can now
include inline image visibility".

Also, it is a good idea to document the new feature in the manual (12.7
Images section and 2.2.1 Global and local cycling section).

You can, for example, check org-inline-image-overlays and (overlays-in
(point-min) (point-max))

I've seen this around the time we removed org-contrib.
I suggest you to re-clone Org repo into a clean folder.

Please do not use org-cycle in tests. It is an interactive command and
makes a number of assumptions about `this-command' and `last-command'
values. Instead, prefer more direct `org-show-subtree'/`org-show-children'.
