[l2h] Re: General HTML generation questions

First of all thanks a lot for the quick and valuable answers!

Sure. Consider a document
\documentclass{article}
\usepackage{html}
\HTMLset{target}{\_blank} 
\begin{document}
An put a \htmladdnormallink{Link here}{http://foo.com/bar.html}
\end{document}

The HTMLset only works when calling e.g.
latex2html -html_version 4.0,frame mydoc.tex
This produces in the content file (mydoc_ct.html):
<BODY bgcolor="#ffffff" text="#000000" link="#9944EE" vlink="#0000ff"
alink="#00ff00">
This arises the issue that it will be very difficult to change colors to
something different or even omit specifying the colors. It would then be
better to have a <body class="contentframe"> in each of the frames' HTML
files and define the appropriate styles in the CSS file. Remember that
bgcolor is rated as "deprecated", so it should not be used for HTML
4.0.
But for the original problem, the link target, the ideal solution would
look like:
\documentclass{article}
\usepackage{html}
\begin{document}
An put a \htmladdnormallink[_blank]{Link
here}{http://foo.com/bar.html}
\end{document}

or 
An put a \htmladdnormallink[target=_blank]{Link
here}{http://foo.com/bar.html}

Of course, I am aware that the response to the second possibility will
be that I shoud use the HTMLcode command. :-)

Anyhow, these are only suggestions...

Agree. Thanks for this.

I did it with HTMLtidy, which works well, thanks for the advice. So
there is no need to do anything to l2h here.
So I recommend everyone to have 'tidy -m' in his HTML_VALIDATOR
variable.

Thanks a lot. I do not know why I oversaw this in the manual. Sorry.

Only imported graphics are affected, correct. Leaving away -E makes no
difference. I played around a little more and found the following, with
myfig.eps being a EPS file.
\documentclass{article}
\usepackage{graphicx}
\usepackage{calc}
\begin{document}
$\rightarrow$

\includegraphics[width=\linewidth,keepaspectratio=true]{myfig}
\end{document}

With 1.67, produces everything as expected.
With 1.68 it logs:
 *** processing 2 images ***

And now the crazy thing: If I remove the \usepackage{calc}, ver1.68
converts the image, but with this image shows a box on the left side of
the real content, and in the box there is the text
keepaspectratiokeepaspectratio.
I put all examples on the web. Prefix is

See test_167.html, test_168.html, test_168_wo_calc.html. The sources are
test_graph.tex and something.eps. The complete package is in
test_graph.tgz

Finally, if I have \usepackage{calc} in and remove the $\rightarrow$,
ver1.68 says  
*** LaTeX produced no output ***
*** no new images can be created
*** Examine the  images.log  file.
and even shows no error besides not creating the image.

Thanks a lot for any advice
