This problem started for me a little while ago: images generated from R source
blocks no longer appear even though I have images display turned on.
For example, this file:
# -----
#+begin_src R :results graphics file :file /tmp/src.png
x <- seq(-4, 4, length=200)
y <- dnorm(x, mean=0, sd=1)
plot(x,y, type = "l", lwd = 2, xlim = c(-3.5,3.5))
#+end_src
#+RESULTS:
[[file:/tmp/src.png]]
# -----
I don't see the image, I just see the text "file:/tmp/src.png". When
image-display is off (C-c C-x C-v) it becomes a link, and when I toggle it back
on it's just plain text.
The file on disk really is there and is a valid image.
If I run the three R lines in an ESS window (M-x R) then the image pops up in
its own window, as normal.
I ran "emacs -Q" and loaded up Org and enough Babel stuff to the source block to
work, and the image appeared inline as it should! So it's something to do with
my config [1] but I can't figure out what.
Has anyone ever had this happen, or noticed it recently? I'm compiling Emacs
and Org from source and both are current. I'm not sure what the easiest way to
identify the problem is.

The usual method is to bisect your setup-orgmode.el file: comment out
the bottom half and if that makes it work, then you know that the
problem is in the part that you commented out. Recursively, bisect
further.
I downloaded your setup-org.el and tried it out. There are two things
that I commend out: the (use-package org-bullets ...) stuff - the
`emacs -Q -l setup-orgmode.el' complained about use-package and I was
too lazy to add whatever is necessary to get it and the (add-hook
'org-mode-hook wrap-region-mode) stuff because I don't have
wrap-region-mode installed. With those two deletions, I see no
problem. I doubt that the problem is with org-bullets, so try getting
rid of wrap-region-mode and see if that does the trick. Of course, it
may be that there is some interaction between your Org mode setup and
all the *other* setup that you do, but bisecting is still the way to
go.

My problem report wasn't very good, I admit. I was hoping someone might
recognize the problem so I could avoid bisecting. Thanks for having a look at
my config and taking some time to do some testing.
It turns out I found the cause by accident! I've been using
./configure --with-imagemagick
to configure Emacs before compiling it. I tried it without that option, and now
the problem has gone away and images are displaying as they should.
The details of how Org and images and ImageMagick work together are beyond me,
but I hope noting this is useful.
