That is not how you would query for a featured image.

Make sure it’s inside the loop. <?php if (have_posts()) : ?> <?php while ( have_posts() ) : the_post() ?> <?php the_post_thumbnail(); ?> <?php endwhile;?> <?php endif; ?>
The most common way to achieve those features is to implement some sort of interface, usually in JSON or XML. To do this, you either use a plugin (http://wordpress.org/plugins/json-rest-api/ <= Will probably part of core in WP 4.0) or do the AJAX function yourself. An example would be: add_action( ‘wp_ajax_get_thumbnail’, ‘ajax_get_thumbnail’ ); add_action( ‘wp_ajax_nopriv_get_thumbnail’, ‘ajax_get_thumbnail’ … Read more
