Extract from answer:
Technet says this Breadcrumb navigation displays a dynamically
generated set of links at the top of Web pages, to show users their
current position in the site hierarchy. By using SharePoint Designer
2010 or Visual Studio 2010, you can configure the breadcrumb
navigation control. For example, you can specify a custom navigation
provider, and you can remove breadcrumb navigation from a page layout.
This article discusses creating a custom navigation provider.
This is a control that you can add to sharepoint found on CodePlex
