Page Title Text Over Image?

You mean text over image? This is pure CSS hack, I used that somewhere but can’t remember where right now. Will reply when I find.

(Lovely design on you site, BTW)

Here is one solution, you might want to try search for “text over image”.

/* Force our nav menu item filter */
add_filter( 'nmi_filter_menu_item_content', '__return_false' );

/**
 * Filter menu item text.
 */
function md_menu_item_content( $content, $item_id ) {
	if ( has_post_thumbnail( $item_id ) ) {

		$content = get_the_post_thumbnail( $item_id, 'sidebar-thumb', array( 'alt' => trim( strip_tags( $content ) ), 'title' => trim( strip_tags( $content ) ) ) );

		if ( $description = get_post_field( 'post_content', $item_id ) )
			$content .= '<span>' . $description . '</span>';

	}

	return $content;
}

/**
 * Register menu item filter.
 */
function md_menu_item_register_filter( $item_classes, $item, $args ) {
	if ( has_post_thumbnail( $item->ID ) )
		add_filter( 'the_title', 'md_menu_item_content', 15, 2 );

	return $item_classes;
}
add_filter( 'nav_menu_css_class', 'md_menu_item_register_filter', 15, 3 );

.sidebar-vertical a {position:relative;display:block;color:#21a6df;font:bold 16px/1.2 arial;}
.sidebar-vertical a img{vertical-align:bottom;}
.sidebar-vertical a > span{position:absolute;left:10px;bottom:15px;z-index:2;max-width:190px;padding:10px;background:#fff;}
