Manipulate breadcrumbs
First have a look in your theme settings example.com/admin/build/themes/settings/my_theme.
In Breadcrumb settings you can decide to display breadcrumb and breadcrumb separator. Select if you want to show home page link in breadcrumb and append a separator to the end of the breadcrumb, useful when the breadcrumb is placed just before the title. Append the content title to the end of the breadcrumb
Useful when the breadcrumb is not placed just before the title.
<?php
/**
* Make breadcrumbs include the current page as an inactive crumb
* Also, remove the top level for image_galleries.
*/
function phptemplate_breadcrumb($breadcrumb) {
if (!empty($breadcrumb)) {
$breadcrumb_new = array();
// Create new breadcrumb array without the top level image gallery link
foreach ($breadcrumb as $crumb) {
if (strstr($crumb, '<a href="/image">') != TRUE) {
$breadcrumb_new[] = $crumb;
}
}
$breadcrumb_new[] = '<span class="active">'. drupal_get_title() .'</span>';
return '<div class="breadcrumb">'. implode(' » ', $breadcrumb_new) .'</div>';
}
}

By default, Drupal only shows breadcrumbs for the Navigation menu. The easiest way to add breadcrumbs for other menus is the menu_breadcrumb module. Just install it and your breadcrumbs should appear immediately.
A more advanced option would be custom_breadcrumbs, which has a lot of configuration options but may not do what you want on install, you'll have to configure it.
