LinuxQuestions.org - docbook2pdf no pictures in output pdf

Hi folks!

I started to learn writing DocBook documents. But now I have a problem with the note-, warning-tags. In the HowTo I used to learn DocBook the example says, that the following code should produce a "!" in a stop sign:

Code:

<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN" "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd">

<book lang="en">

        <title>

                A very short article

        </title>

        <chapter>

                <title>

                This is a sample chapter

                </title>

                <para>

                My own line added to the article.

                <warning>

                        <title>Did you know?</title>

                        <para>Did you know, that XML-Tags musst be closed?</para>

                </warning>

                </para>

        </chapter>

</book>

But in the output PDF-document only a box with the text between the warning-tags appears.

I use Debian Etch (with latest updates) and all docbook-packages are installed.

Any answers, why there is no warning image?
