This will have trouble, due to the \fitfig command,
as a user-defined macro.
See below for more details.

This is fine, as the parameter data is constant.

This is not fine, as the value to be returned is not knowable
to LaTeX2HTML at the time it substitutes parameters into
user-defined macros.

You need to tell LaTeX2HTML about the \fitfig command
before it encounters it in the document itself.
This way it will not be regarded as a user-defined macro.
Do this as follows, within .latex2html-init
or any init-file used by your job:
&ignore_command(<<'_IGNORE_COMMANDS_');
fitfig # {}
#
# other commands can go here, 1 per line
#
_IGNORE_COMMANDS_
Also, you will need to limit the applicability of the
normal LaTeX definition of \fitfig to appear only
within the correct contexts, including images.tex .
\begin{imagesonly}
\newcommand{\fitfig}[1]{......
.....
\end{imagesonly}
%begin{latexonly}
\newcommand{\fitfig}[1]{......
.....
%end{latexonly}
Presumably you are already loading \usepackage{html}
which is needed for the {imagesonly} environment
to be defined for a LaTeX job.

Try the above.
Hope this helps,
