I bisected and indeed 636736861688abe73cc5dd4181fdb66de3fd8cfd is the
first bad commit.

However, I also noticed that emacs -Q does not exhibit the problem
because file-name-handler-alist does not have an entry for images.  So I
must be loading some package whichs adds a handler for images.  In fact,
if I turn off auto-image-file-mode, images appear as I expect.
