What environments is the command nested inside ?

I'm guessing it's inside a {figure} environment,
in which case  LaTeX2HTML  expects to make an
image of the whole figure's contents.

Hence  \includegraphics{lmtinitial.gif}  gets
passed to LaTeX for processing, and fails there,
since LaTeX doesn't handle .gif images.

That's because there is no environment affecting how the
processing is to be handled.
When \includegraphics  appears by itself, you'll get the image
processed in whatever way is most appropriate for its format-type.
The image stands by itself, without any surrounding context.

When it's inside another environment, there is an implicit
relationship to other material. This all gets passed to LaTeX,
unless there is extra markup that specifies otherwise.

Why did you comment-out the
    \htmladdimg{lmtinitial.gif}
which is the best way to include images directly.
Except, it probably should be
        \htmladdimg{../lmtinitial.gif}
because the path needs to be relative
to where the HTML files will be located.


Alternatively, try:

\begin{figure}
%begin{latexonly}
      \includegraphics[scale=0.75]{lmtinitial.png}
%end{latexonly}
\begin{htmlonly}
   \begin{makeimage}
   \end{makeimage}
    \includegraphics{lmtinitial.gif}
\end{htmlonly}
    \caption{...}\label{...}
\end{figure}

Images are treated as horizontal material in HTML.
Just use  \html{\\}  to force line-breaks,
when it doesn't happen automatically.
