[l2h] Some bitmapped images produced by latex2html contain solid edge at the bottom of the image

FYI;
I found that the following setting ELIMINATED all the cropping bars from the
math bitmapped images produced
$MATH_SCALE_FACTOR = 1.8;
$DISP_SCALE_FACTOR = 1.0;
In general, the higher $MATH_SCALE_FACTOR , the less the number of these
bars. at 1.8, I do not see any. Please see this output I generated using the
above settings
http://12000.org/my_courses/FULLERTON_COURSES/spring_2009/MAE_511_advanced_vibration/project/control_inverted_pendulum/index.htm
and click on the link that says HTML generated by latex2html. You see there
are no more bars !
May be the above will give some l2h expert a hint where the problem could
be?
thanks,
