If you use sgml2html of sgml-tools (v1) in order to convert your HOWTOs
in Linuxdoc DTD sgml, then do not specify neither "-I" nor "--button" 
option to get just the word in the place of images.

The required work to use PNGs in the place of GIFs is not so difficult.

1) convert icon files (next.gif, prev.gif, toc.gif) into PNGs
   (next.png, prev.png, toc.png)

2) Apply the following patch to $LIB/SGMLTools/Html2Html.pm

  The patch above is against my Debian package (sgml-tools_1.0.9-9),
  so if you use other version of sgml-tools (v1), this patch can not
  be cleanly applied, and requires the manual editing.

  I will work to update the JF patch for sgml-tools_1.0.9, (the current one
  is downloadable from:
  but it may takes some more time, since I am busy now for preparing the new
  release (potato) of Debian.

3) Rebuild (re-convert) all the HOWTOs using patchd sgml2html.

Maybe simple work, but it will require someone's time and effort,
especially in rebuilding all the HOWTOs.
