how do I query the featured image?

try query post or get post to do multiple loops. show 1 post of the custom post type on the first loop and do a second loop to show al your featured images

I will give that a shot

well, I am running into trouble. Take a look. Do you have any advice on it?

<?php $args = array('post_type' => 'half slider');
				$loop = new WP_Query($args);
					while($loop->have_posts() ) :
						 $loop->the_post_thumbnail('half_slider');
               		endwhile; ?>

try for your first loop:

<?php
$args = array('post_type' => 'half slider', 'posts_per_page' => 1);
$loop = new WP_Query($args);
?>
<?php while ( $loop->have_posts() ) : $loop->the_post() ?>
<?php
if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
  the_post_thumbnail();
}
?>

<?php  the_content(); ?>
<?php endwhile; ?>

nope. it’s not working. there is a syntax error somewhere in there so I can’t test it because I can’t find it. I don’t think it would work anyway. I am trying to set it up so that when the user creates a post, the excerpt will show on the left side of the page. Which I have set up now. And then the featured image will show up on the right side of the page. But I am trying to load the featured image into the Nivo slider. The problem is that when you create a new post to add a new featured image, it wants to overwrite the post on the left. Which I don’t want. So your idea of two loops was a good one. So I have been looking for ways to query the ‘half slider’ post type and get just the featured images from that post type to load them into the slider.

well, good luck in your quest
