Works on pages but not on categories/posts?

Hello :-), the plugin is great but i have a small problem. On Pages it works like a charm. But the Images did not appear on category or post pages. I use the Twenty Fourteen Theme.

a small snippet from my header.php file

this do not work on category pages or posts:
<?php do_action('apply_header_images'); ?>

this work on any page/post and category page:

<a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home"><img src="<?php header_image(); ?>" width="<?php echo get_custom_header()->width; ?>" height="<?php echo get_custom_header()->height; ?>" alt="">
		</a>
