I apologize for bothering you all again, but this doesn't seem to work
for me.  Here's an example of what I do:

\begin{figure}
  \htmlimage{notransparent}
  \begin{center}
\begin{latexonly}
    \epsfig{file=opal-inheritance.ps,width=.9\textwidth}
\end{latexonly}
    \htmladdimg{../gifs/opal-inheritance.gif}
  \end{center}
\caption{The inheritance hierarchy among some of the Garnet prototype objects.
All of the standard shapes in garnet are instances of the
\pr{graphical-object} prototype.  As an example of inheritance, the
\pr{circle} and \pr{oval} objects are both special types of arcs, and
they inherit most of their properties from the \pr{arc} prototype
object.  The Gadgets (the Garnet widgets) are not pictured in this
hierarchy, but most of them are instances of the \pr{aggregadget} object.}
\tag{opalInheritance}
\end{figure}

This yields LaTeX output that's just fine.  But when I use LaTeX2HTML,
I get the following HTML generated:

<DIV ALIGN="CENTER"><A NAME="1032"></A>
<TABLE>
<CAPTION ALIGN="BOTTOM"><STRONG>Figure 2.1:</STRONG>
The inheritance hierarchy among some of the Garnet prototype objects.
All of the standard shapes in garnet are instances of the
<TT>graphical-object</TT> prototype.  As an example of inheritance, the

<TT>circle</TT> and <TT>oval</TT> objects are both special types of arcs, and
they inherit most of their properties from the <TT>arc</TT> prototype
object.  The Gadgets (the Garnet widgets) are not pictured in this
hierarchy, but most of them are instances of the <TT>aggregadget</TT> object.</CAPTION>
<TR><TD><IMG
 WIDTH="14" HEIGHT="10" BORDER="0"
 SRC="img1.png"
 ALT="\begin{figure}\begin{center}
\htmladdimg{../gifs/opal-inheritance.gif}
\end{center}
\end{figure}"></TD></TR>
</TABLE>
</DIV>


I.e., it seems to ignore my \latexonly command, try to translate the
image anyway, and ignores my htmladdimg.  Am I committing some howler
here?  Any suggestions will be very much appreciated!

Best,
R
