That's good.

Try simply putting the following in the document preamble:

\usepackage{html}
\begin{imagesonly}
  \let\PSTpspicture\pspicture
  \let\PSTendpspicture\endpspicture
  \def\HTMLpspicture{\begingroup\setbox0=\hbox\bgroup\PSTpspicture}
   
\def\HTMLendpspicture{\PSTendpspicture\egroup\colorbox{white}{\box0}\end 
group}
  \let\pspicture\HTMLpspicture
  \let\endpspicture\HTMLendpspicture
\end{imagesonly}

This obviates the need to explicitly put in the \framebox (or   
\colorbox{white}{....} )
around every {pspicture}.

The code rebinds \pspicture to first set the picture's contents within  
a temporary
box-register  (in fact within \box0 ) before putting a white rectangle  
under it,
via the   \colorbox{white}{\box0} .

It all happens inside a \begingroup .... \endgroup to preserve any  
previous
contents of \box0 . So there may be problems with any \label, \index or  
similar
commands within the {pspicture} creating flags to be accessed from  
outside it.
But that's a pretty rare thing, that probably doesn't work in  
LaTeX2HTML anyway.

Also, it only happens when using LaTeX2HTML via the  {imagesonly}   
environment
construction, from the  {html}  package.

This little hack may save you some more. :-)
