How is load-file-name of the package's .el file related to its
inability to load images?

Also, can you please provide a recipe that takes neotree.el out of the
equation?  AFAIU, it should be enough to have a .el file that is
loaded in .emacs, and have the contents of that file be just

  (print load-file-name)

Is that correct?

But that bug was solved, so something else must be at work here.

Thanks.
