This is a common problem, due to the different resolutions
required for onscreen and printed outputs.

There are various things that you can try.

A.
Firstly, there is a variable  $IMAGE_SCALE_FACTOR
that allows you to specify a scaling for the images
that LaTeX2HTML generates.
The default value is 1.6. You may want to make
it either larger or smaller, according to your
own requirements.

B.
Another nice trick is to only place "thumbnail"
images on the HTML pages. These are hyperlinks
to a full-sized version of the image.
This allows the images to not dominate the web-page,
while allowing just 1-click access to the full detail.

\htmlimage{thumbnail=.25}  is enough to get thumnails
at 1/4 size of the full-sized image.


C.
Another strategy is to use "conditional" coding,
as follows:

\begin{figure*}
\begin{makeimage}
\end{makeimage}
\htmladdimg{../images/inn1.png}
%begin{latexonly}
\includegraphics{images/inn1.ps}
%end{latexonly}
\caption{....}\label{...}
\end{figure*}

Here inn1.png  is a .png version of your image which
you may have created with an earlier run of LaTeX2HTML,
at exactly the desired size for web-pages.

The empty \begin{makeimage}...\end{makeimage} tells
LaTeX2HTML to *not* create an image for this {figure},
but to still create the correct HTML layout for
the contents, which is just  inn1.png  + captions, etc.

In a normal LaTeX run, both  \htmladdimg  and
the {makeimage} environment are ignored, so you just
get  inn.ps  as expected.

Hope this helps,
