iimage.el patch

[KOSEKI Yoshinori]

Please commit this patch.

2004-06-25  KOSEKI Yoshinori  <address@hidden>

        * iimage.el (turn-on-iimage-mode, iimage-mode): add autoload.

        * iimage.el (iimage-mode-image-search-path): New user option to
        search the image file.
        (iimage-locate-file): New fun. Emacs21.3 or earlier does not heve
        locate-file.
        (iimage-mode-buffer): Use it.
        Suggested by Masayuki Ataka.
