The way your pages link together tells the search engines what the page is about and also allows them to easily (or not-so-easily) work their way to your internal pages. If your site has an image or script-based navigation it is important to also use text links either in your content, in a footer, or both. The text links are easy to follow for a spider and perhaps more importantly, the text links allow you the opportunity to tell the spiders what a specific page is about though the anchor text and, in the case of footers, allows you to add in more instances of the targeted phrases outside of your general content area.
