Hi there,
You’ll have to do a bit of customization with PHP filters to do this.
Untick Include title and add this PHP snippet.
add_action('wpsp_inside_image_container', function($settings){
$before_title = sprintf(
'<%1$s class="wp-show-posts-entry-title" itemprop="headline"><a href="%2$s" rel="bookmark">',
$settings[ 'title_element' ],
esc_url( get_permalink() )
);
$after_title = '</a></' . $settings[ 'title_element' ] . '>';
echo the_title( $before_title, $after_title );
});
You then add this CSS:
.wp-show-posts-image.wpsp-image-center h2.wp-show-posts-entry-title {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 100%;
}
