Dear all,
I there a global option to disable the insertion of the ALT comments for the
automatic generated comments. I don't think these comments provide any
useful information for the end reader (it might for the TeX writer :-) ) of
the html-documents.
Firstly, ALT text is a *required* attribute for <IMG> tags, according to the HTML specs, so failure to include them renders your document invalid, from this point-of-view.
Secondly, for browsers that *do not display* images, it is the ALT text
which is shown instead, so they convey definite information in this case.
This includes screen-readers, for the sight-impaired, for whom the ALT
text is the *only* means to get an idea of what the picture was showing.
Thirdly, if the pop-up of ALT text is annoying to yourself, or any of your readers, then the option is always available to simply turn it off in your browser. In some browsers the place to do this is via a check-box labeled (rather badly) as "Tool Tips".
Fourthly, and this is the only aspect that is specific to LaTeX2HTML, is that for small inline images, the ALT text is the only place where the original TeX coding is included in the HTML source document. (For larger --- e.g. displayed-math --- images, there are special comments, of the form <!-- MATH: ...... --> which give the complete source string.)
Hence, at least in principle, it is possible to recover the complete
LaTeX source for the document from the HTML source.
(Things like lists, tables and sectioning need to be reverse-engineered.)
The simple answer to your question is that *no*, it's not easy to turn off the generation of ALT text, because it is bad form to generate HTML pages this way. But it shouldn't be too hard for a Perl programmer to find the place in the LaTeX2HTML source (i.e. in latex2html.pin or your installed /usr/local/bin/latex2html , or whatever ) where these attributes are generated, and then modify what it creates.
Hope this helps,
Ross Moore
