Hmmm, as far as I understand, \begin{gif}{filename}..\end{gif} is for 
things that are not easily typeset in HTML, for example, some 
mathematical formulae. If \makegifs or \makeimages (in version 2.7) is 
defined, images will be generated via latex otherwise the gif or image 
environment is

\def\@@@@image{\tex}
\def\endimage{}

So it simply switches to TeX and does nothing. To me that means that the 
generated images are solely for the HTML version, so why does counting 
not work?

If \makeimages is defined the corresponding images appear (by some 
magic) on the first few pages of the dvi file and are extracted by

   dvips -p

To syncronise, it would be only necessary to step a counter via elisp 
for each \begin{image}.

I know that there still could be a problem when one has something like

\begin{ifhtml}\begin{image}..\end{image}\end{ifhtml}

One could repair this by saying that if \makeimages is defined one 
defines in hyperlatex.sty

\newenvironment{ifhtml}{}{}
\newenvironment{iftex}{\comment}{\endcomment}

where the 'comment' stuff is taken from \usepackage{verbatim}. One 
should remember that for the html generation, the generated dvi file is 
for creating the images and thus an auxiliary file.

Do I see something wrong here?
