Yes. That space is important for correct alignment of baselines.
It can make lines wider, but the solution here is to set a constant
line-width in the .css file.
LaTeX2HTML cannot do this automatically, without also setting the
font-size. But this is something that users ought to be able to choose
for themselves, when surfing your pages.

I'd prefer to locate why your images are coming out badly.
It sounds like a small misalignment of the "cropping-bars".

Are you using anti-aliased scalable fonts ?
This should give good results.
If you are stuck with bitmaps, then the quality is not so good.
Please post a link to a page that shows the poor quality
that you are getting. If you can make the images.log file
available too, then that can help in diagnosing the problem.
Better stil is to run the job with -debug and allow access
to the full directory, and subdirectories that result.
Also make available a copy of the screen messages.
