Hyperlinking Images

[Adjust]

Hi Guys,
I've made chapter start images which take the place of decorative fonts for the chapter number and title, so that the design elements stay intact.

I then Hyperlink the contents page to the relevant chapter.xhtml files.

But my problem is I've been unable to hyperlink the chapter start image back to the contents.xhtml by simply pointing back to it via dreamweaver. The best I can come up with, is adding a fullpoint and then hyperlinking to from it to the content.xhtml

Has anyone got any ideas?
Thanks
