Good question.
This would require an optional parameter to  dvips .
Dunno for sure, but it looks like  -n 10000  might help.

   http://amath.colorado.edu/documentation/LaTeX/basics/steps/help_dvips.html

So within your l2hinit.pl  initialisation file, you want to include a line:

  $DVIPSOPT .= ' -n 10000 ';

or you could add this extra parameter within the subroutine
  sub make_off_line_images  (line# ~3780 in latex2html)

Hopefully this will cause 4+ numbering digits in the file names
written out by  dvips .
