There is a reason for the truncation, at least on older Perl systems.
You can experiment with changes to the following block of coding,
from the latex2html script, part of the  sub  extract_parameters  block:

  if (!$alt) {
    #...catching all the code for the ALT text.
    $alt = &flatten_math($contents); undef $keep_gt;
    #RRM: too long strings upset the DBM. Truncate to <= 165 chars.
    if ( length($alt) > 163 ) {   
        $start = substr($alt,0,80);
        $end = substr($alt,length($alt)-80,80);
        $alt = join('',$start,"...\n ...",$end);

Hope this helps,
