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 [This doc](http://www.emacswiki.org/emacs/AutoImageFileMode) says it has been replaced by image-mode.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: 
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.
Using Emacs 23.1 (on Fedora 12) when I visit a `*.png` file, it shows up as an image in the Emacs buffer. Similarly for `*.gif` and `*.pdf` files. The mode was advertised as Image[png], fwiw.
