Hi Robin, and others.

Yes, it's true that html.sty does have a slight problem in this
regard,
but that *should not* be relevant to the generation of images by
a LaTeX2HTML job.
The images.tex file that is created by LaTeX2HTML should not include
lines that cause either html.sty or hyperref.sty to be loaded.
However, that being said, it *is* possible that a user's own package
or \input source might be requiring some coding that has a side-effect
of causing such a package to be loaded as part of the processing
of images.tex .
The *easy* way to avoid this is to identify lines of coding that lead
to this effect, but which are irrelevant to any images that need to
be created. Then simply surround these lines by "comments" as follows:
%begin{latexonly}
...
...
%end{latexonly}
This causes the intervening ... lines to be ignored by LaTeX2HTML,
while having no effect at all when LaTeX processes the same job.

Yes; html.sty needs an update.
To be fully compatible with *verrrry* old LaTeX software, the test for
whether pdfTeX is being used should be something like:
\ifx\csname IfFileExists\endcsname\relax
\let\pdfunknown\relax % too old for packages ??
\else % using a modern LaTeX
\IfFileExists{ifpdf.sty}{%
\usepackage{ifpdf}%
\ifpdf\else
\let\pdfunknown\relax % not making PDF
\fi
}{%
\ifx\csname pdfoutput\endcsname\relax
\let\pdfunknown\relax % not using pdfetex
\else % either pdftex or pdfetex
\ifnum \pdfoutput=0\relax
\let\pdfunknown\relax % not making PDF
\fi
\fi
}%
\fi
Now the test for what to do about PDF and hyperref becomes:
[EMAIL PROTECTED]
\ifx\undefined\hyperref
\ifx\relax\pdfunknown
[EMAIL PROTECTED]
\else
% making PDF so force loading of hyperref package
\RequirePackage{hyperref}%
\fi
\fi
This means that if methods other than pdfTeX are being used
to make PDF (e.g., via dvips + Ghostscript) then the user
must ensure that \usepackage{hyperref}
comes before \usepackage{html} .
Does this all look OK to you Robin ?
