Thanks for the update!
For tests, you will need to test the existence of image overlays.
You can refer to test-org-fold/org-fold-reveal-broken-structure but
need to test overlays-at instead of just org-invisible-p.

I will comment in the code.

You are providing both hook and a customization. It is redundant. Users
can already remove the hook when desired.
In this area, we generally do not use custom variables (see M-x
customize-group org-cycle). So, it is better to use hook.

You can just
(dolist (ov overlays)
(when (memq ov org-inline-image-overlays)
(setq org-inline-image-overlays (delq ov org-inline-image-overlays))
(delete-overlay ov)))
Note that `delete' and `delq' are not safe to use on their own. You
should always use (setq foo (delq 'member foo)). It is detailed in the
docstring.
