[BUG] Inline images cannot be displayed [9.5 (release_9.5-108-g93132c @ /tmp/org-mode/lisp/)]

[Liu Hui]

Hi,

Org mode cannot display inline images because of an error caused by
org-display-inline-image--width. It seems display-line-numbers-width
is regarded as a number unconditionally.

Recipe:

1. emacs -Q

2. Make the following settings:

   (setq org-image-actual-width nil)
   (setq org-startup-with-inline-images t)

3. Open some org-mode file containing image links, e.g.

   #+attr_org: :width 50%
   [[file:~/test.jpg]]

Confirmed

I was able to reproduce this with the latest main branch. It works fine with
attributes like this:

#+attr_org: :width 500px

And the 9.5 tag does not have this bug, so I think this might be related to
recent changes to image width. Adding Timothy to CC who worked on those
changes.

Thanks for confirming and the CC, hopefully it’s not what I did 😅, but that’s
what the bugfix branch is for. I’ll try to have a look within the next week or so,
but I’m unfortunately busy over the next ~month so I can’t make any grantees.

All the best,
Timothy

I cannot reproduce this on the latest main.
Closing.

Please let me know if the bug still persists on your side.
