How to add post title below the featured image in the plugin code?

Question

I'm trying to modify the 'display random posts' plugin. In the following code I would like the output display to show list of posts with the featured image and the title of the post below it. Currently this code displays only the featured image in front end. How do I add the post title below the image?

$string .= '<ul>';
while ( $the_query->have_posts() ) {
    $the_query->the_post();
    $string .= '<li><a href="'. get_permalink() .'">'. get_the_post_thumbnail() .'</a></li>';
}
$string .= '</ul>';

Personally I would not modify the plugin, as you'll just lose all your changes on each and every update.

But if you insist, just change line 4 to

$string .= '<li><a href="'. get_permalink() .'">'. get_the_post_thumbnail() .'</a><h6>'. get_the_title() .'</h6></li>';

Then you can target those h6s with CSS
