Adding a picture inside the DocBook is simple, using the <mediaobject> element, which also includes objects such as processing video, audio, and so on. Okay, here's a look at the example:
<mediaobject>
<imageobject>
<imagedata fileref="images/img1.png"/>
</imageobject>
</mediaobject>
But there's nothing you can do to add links <mediaobject> elements to the picture.
Check the docbook5.0 document, find a link to add a replacement element <inlinemediaobject> but one thing to be aware of is that elements must be <link> fit to have a link capability
<para>
<link xlink:href="http://java.sun.com/docs/books/tutorialJWS/uiswing/learn/ex6/CelsiusConverter.jnlp">
<inlinemediaobject>
<imageobject>
<imagedata fileref="images/jws-launch-button.png"/>
</imageobject>
<textobject>
<phrase>Java™ Web Start</phrase>
</textobject>
</inlinemediaobject>
</link>
</para>
Ok, so the picture can be connected with it. Let's see a picture.
