First, thanks for providing a good report with the minimal example.

For the record, "texdoc graphics" gives the documentation
for \includegraphics, which gives the information about how to
use .bb files and external commands to change formats.

Note that running commands from a tex document requires that
(restricted) \write18 be enabled.  This may not always be acceptable
due to the potential for some malicious .tex document running a nasty
command.

It is not so easy to determine which formats beyond EPS are
supported directly by dvips.  The sources for dvipsk include emspecial.c,
which says:

/* em:graph routines */

/* The graphics routines currently decode 3 types of IBM-PC based graphics   */
/* files: .pcx, .bmp, .msp. The information on the formats has occasionally  */
/* been sketchy, and subject to interpretation. I have attempted to implement*/
/* these routines to correctly decode the graphics file types mentioned.     */
/* The compressed .bmp file type has not been tested fully due to a lack of  */
/* test files.                                                               */

With TeX Live latex+dvips you can use:

\documentclass{article}
\usepackage{graphicx}
\DeclareGraphicsExtensions{.bmp}
\DeclareGraphicsRule{.bmp}{bmp}{.bb}{}%      BMP
\begin{document}
\begin{figure}
\includegraphics{golfer.bmp}
\end{figure}

\end{document}
