[l2h] Relative URLs in png/gif images

Thanks, Ross, for your prompt reply.  I tried your suggestion, but
it fell a bit short of expectations:

\DeclareGraphicsRule{.png}{eps}{.bb}{`pngtopnm #1|pnmtops -noturn -rle}

%  The \showimage command displays a gif image in html,
%  and a PostScript version of it in the ps document.  The optional
%  argument 'width' overrides the natural width of the image.
%  Usage:  \showimage{image}{caption}
%          \showimage[width]{image}{caption}
	    \includegraphics[width=\gifwidth]{#2.png} \\

I'm going to include a png image right here:
\showpng{l2h}{The figure caption}{../}

% --------------------------------------------------------

What happened was that l2h still tried to "convert" the image with
pstoimg.  Of course it failed, since the image was empty as far as
LaTeX was concerned.

Not only that, but it didn't even make a link to my image:

I'm going to include a png image right here:

<DIV ALIGN="CENTER"><A NAME="l2h"></A><A NAME="27"></A>
The figure caption</CAPTION>
<!--Table of Child-Links-->


I recall having tried several combinations of \begin{htmlonly},
\begin{latexonly}, etc. but the one which seemed to work best
was my original post.  It's one big disadvantage is that it
relies on a nonstandard LaTeX2HTML, and we both know that there
are too many of those floating about already!
