openjade: missing image

Hi all,

I'm trying to generate an RTF from docbook with
an image by openjade.

The xml source is as below:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook

XML V4.2//EN"
"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd">
<article id="index">

	<articleinfo>
		<title>My Sample DocBook</title>
	</articleinfo>
	<sect1 id="about">
		<title>About this document</title>
		<para>
			<inlinemediaobject>

				<imageobject>
					<imagedata format="BMP" align="left"
fileref="logo.bmp"/>
				</imageobject>
			</inlinemediaobject>
		</para>
		<mediaobject>

			<imageobject>
				<imagedata format="SVG" align="left"
fileref="logo.svg"/>
			</imageobject>
		</mediaobject>
	</sect1>
</article>


However I keep getting RTF without images. Can
anyone refer to the source of the problem and a
possible solution?

Thanks a lot in advance,
Pavel.

I'm using 
"openjade" version "
1.3.3-pre1"
"OpenSP" version "1.5.1"
docbook-dsssl-1.79
docbook 4.4
