It was the guide by de Quero and Mayer that I was interested in.
Where is this to be found?

Yes, there are 2 places where the .eps files need to be accessed.

Firstly, TeX (or LaTeX2HTML) needs to access them to read size information
for typesetting --- this is handled correctly whether you use epsf.sty
or \includegraphics.

Secondly, is when dvips need to find them for inclusion into a .ps file.
This is where you run into a problem, due to working within a subdirectory.

My work-around is to run LaTeX2HTML once, so that the directory is created
and most of the translation is done. Then I make symbolic links of all
the .eps files into that directory, then rerun LaTeX2HTML.

Now all the images are found and the translation can be completed.
Generally you will need to fix a few things in your LateX source,
so running a 2nd, and subsequent times, is no problem.

It is the symbolic-link step which is missing.
However some systems do not support sym-links;
for these you must copy the files to the subdirectory,
or use a variable to specify the search path...

 ... TEXPSHEADERS may work on some systems, using teTeX .
For other TeX installations you'll need to explore the documentation
to see if there is one available for  dvips  to use.

Hope this helps,
