Subject: 26.0.90; display of pbm images broken?
Date: Fri, 13 Oct 2017 21:10:50 -0500

start emacs -Q
evaluate (arg FILE-OR-DATA of create-image should point to a pbm image)

(defun foo ()
  (interactive)
  (insert-image (create-image "~/foo.pbm")))

M-x foo

This displays the image with emacs 25, but not with emacs 26.0.90:
there is just a small bounding box (smaller than the image) where
the image should be displayed.  It is my understanding that pbm
images do not depend on external libraries.  (Anyway, I built emacs
25 on the same machine without problems.)
