Why do you have some equations with \htmlimage and others not ?

No; the alignment could be shot-to-pieces by the mixture of \htmlimage
and not.
When you use \usepackage{amsmath} then LaTeX2HTML knowns to expect
lots of mathematics, perhaps with complicated alignments, and cetainly
expects to control equation-numbering.
By using \htmlimage you are saying, "ignore what you would normally
do with this environment and pass it to LaTeX for an image".
This forces LaTeX2HTML to select a paper-size on which to layout
the equation and equation-number as it creates the image.
Aligning equation-numbers in images with those not in images
is essentially impossible, especially since you have no control
on how wide your reader has set his/her browser-window; that's
to say nothing of the choice of font size and style.
I don't think that is is what you want to do here at all.

Delete the \usepackage line ?
It's what I get if I retain that line:

The .gif images are in one column of a <TABLE> while the non-image
equation numbers are in another column to the right of the images.

What you are asking for is supposed to be the normal behaviour
of \usepackage{amsmath}.
If that is not what you are getting, would you send a URL to a web-site
that you have created that shows it created incorrectly.

Certainly you should not be using \htmlimage
with environments that include numbering.
Hope this helps,
