png images in docbook sgml

["Martin Bialasinski" <martin@internet-treff.uni-koeln.de>]

Hi,

the gmc package has docs in docbook format. Upstream switched from gif
to png for images, but I now have a problem with the generated files.

The document declares itself as

<!doctype article PUBLIC "-//GNOME//DTD DocBook PNG Variant V1.0//EN" [         
<!ENTITY INDEX SYSTEM "genindex.sgml">                                          
]>                                                                   

and images are inserted by

<Graphic Format="png" Fileref="./figs/gmc1" srccredit="dcm">

The generated html file contains

<IMG
SRC="./figs/gmc_move.gif">

not png :-(

The files are generated by "-db2html gmc.sgml" in the Makefile.

Anyone has an idea on this?

The png files initially don't exist in the figs/ subdir (upstream
error), does this matter?

Ciao,
        Martin
