Question: I read about auto-image-file-mode , which I think displays image files as images within emacs. I'd like to use it. [This doc](http://www.emacswiki.org/emacs/AutoImageFileMode) says it has been replaced by image-mode. 

I can't get either to work. 

Any help?

Answer: 
I got it to work, by downloading the packages for PNG and JPG [from GnuWin32](http://gnuwin32.sourceforge.net/packages.html), and putting the required DLLs into the \emacs\bin directory: 

```
From LibPng: 
  libpng-config
  libpng12-config
  libpng12.dll
  libpng3.dll
  zlib1.dll

From jpeg: 
  jpeg62.dll

```

Now it works. Here's a screen-shot of editing a SO question, being displayed in emacs.

You could also drop those DLLs on the OS's PATH, before running runemacs.exe. That works, too.
It can depend on what version and where you got your windows emacs binary. If you have the windows emacs23 binary from the gnu ftp site then I don't think it is compiled with image support (at least this was the case several months ago). I use the patched windows emacs23 binary from [EmacsW32](http://www.ourcomments.org/Emacs/EmacsW32.html) which does have image support. I also have `(auto-image-file-mode)` in my `.emacs` file.
