Thanks, Nasser M. Abbasi, for kindly taking the time to reply to me. I
found the file /usr/lib/latex2html/l2hconf.pm. In it among other lines the
following lines existed, but not necessarily consecutively:
$DVIPSOPT .=" -E"; (Please notice the period before the equals sign.)
$MATH_SCALE_FACTOR=1.6;
#$DISP_SCALE_FACTOR=1;
So after receiving your e-mail letter I changed two of those lines to read:
$MATH_SCALE_FACTOR=1.8;
$DISP_SCALE_FACTOR=1.0;
.
Results in the .html file produced by LaTeX2HTML: The black line segment
under the integral sign with the limits of integration having algebraic
fractions in them was removed. But the black line segments under integral
signs produced from the LaTeX commands containing \int\limits
_{-\infty}^{+\infty} remained. Those were probably among 27 reported errors
on 27 images. I don't know with which images all of the other errors were.
But I think I remember at least one pnmcrop-related error while latex2html
was processing my .tex file.
Next I changed to $MATH_SCALE_FACTOR=2.0; in the file l2hconf.pm and
otherwise did not change any other lines in that file.
Results: There were errors on 27 images. The black segment under the
integral sign with algebraic fractional limits returned.
Continuing with the same settings in l2hconf.pm I made a test, .tex file
containing some commands very similar to
\begin{equation}
\int\limits _{-\infty}^{+\infty}
\end{equation}
and then produced a .html file from that .tex file using a latex2html...
command. In the resulting .html file a black line segment existed under the
integral sign with the limits of positive and negative infinity. What
should I do now to try to eliminate the unwanted black line segments under
some of the integral signs? Note also that there were also around 20 images
with errors reported while latex2html attempted to generate them; and in
detail I don't yet know what obvious problems there were, if any, with the
associated mathematical symbols associated with the images for which errors
were reported by LaTeX2HTML.

This sounds like the same known problem which was mentioned here some time
ago?
Check http://12000.org/my_notes/l2hwin/index.htm and look for
item (2) under "some errors and possible solutions"
Here it is:
"some of the bitmap images produced for the mathematics in the
document have a solid dark bar, usually at the bottom or the
side of the bitmap image. The reason for this is unknown.
But I found by trial and error that setting the following
values in my l2hconf.pm eliminated most if not all of these
$MATH_SCALE_FACTOR = 1.8;
$DISP_SCALE_FACTOR = 1.0;
"
Something to try to see if it will fix your problem.
