Hi all,

When I try to show inline images automatically resized in an org-mode
buffer, the thumbnail doesn't show (a big blank box shows where the resized
image should be) and the following errors are echoed in the "*Messages*"
buffer.

```
ImageMagick error: no decode delegate for this image format `JPEG' @
error/constitute.c/ReadImage/504
```

The image types I have tried are JPG and PNG.
When tried with a PNG file, the error message changes to
```
ImageMagick error: no decode delegate for this image format `PNG' @
error/constitute.c/ReadImage/504
```

* [Related settings]:

** init.el

`(setq org-image-actual-width nil)`

** the org-mode file

```

#+ATTR_LATEX: :width 300pt

[[file:20160802-142357_2016-08-02_13.35.28-1.jpg]]

```

I tried this with Emacs running in the safe mode, i.e. running with "-q"
option.

The inline image shows correctly (with the original size) until I set
`org-image-actual-width` to `nil`, after which I don't see the image in the
buffer

 (A big blank box appears where the image should be. I also see the errors
mentioned above in the "*Messages*" buffer.).

* [Current workaround I use]:
It doesn't occur when I use the snippet in this SO answer.
http://stackoverflow.com/questions/17637685/configuring-emacs-for-showing-fixed-width-inline-images
It basically rewrites org-display-inline-images function.

* [Environmental information]:
** (i) I built my Emacs using the following tool:
https://github.com/renard/emacs-build-macosx
by running `./build-emacs emacs-24.5`.
It was built with ImageMagick, and I can correctly export LaTeX formula
with it.
Also it works fine when I don't use the resize feature, i.e.
`org-image-actual-width` is set to `t`.

** (ii) Versions
*** Emacs:  emacs-24.5.50.1
*** Mac OS X: El Capitan 10.11.6(15G31).

*** $ convert --version
