I've got a system for post images where I have a specific category's post thumbnail shown in the header, with a cropped version appearing in the blog #preview, and the full size image appearing in the full post.

Images are not appearing in any of the 3 locations, and I'm not quite sure why.



    if (function_exists('add_theme_support')) {

    if ( function_exists( 'add_image_size' ) ) { 
    add_image_size( 'custom-image', 440, 265, true ); //(hard cropped)

    function ravs_get_custom_image( $featured_img ){
    global $post, $posts;
    $args = array(
        'post_type' => 'attachment',
        'numberposts' => 1,
        'post_status' => null,
        'post_parent' => $post->ID,
        'exclude' => $featured_img

  $attachments = get_posts( $args );
     if ( $attachments ) {
        foreach ( $attachments as $attachment ) {          
           $img =  wp_get_attachment_image( $attachment->ID, 'custom-image' );
           return $img;
         echo 'Please attach images to your post';


<?php echo get_header('cait');;?>
<?php echo get_sidebar();;?>

<div id="blog">
    <div class="preview">
        <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
        <div class="post-image">
            <?php echo ravs_get_custom_image( get_post_thumbnail_id () ); ?>
        </div><!-- end post-image -->
        <div class="post">
            <h2><?php the_title() ;?></h2>
            <span class="post-preview">
                <?php the_excerpt('read more...'); ?>
                <?php endwhile; else: ?>

                    <p>Sorry, no posts to list</p>

                <?php endif; ?>
            </span><!-- end post-preivew -->
            <p class="post-meta"><span style="font-family: amatic;">>></span>&nbsp;Posted on <?php the_date('M-d-y'); ?>&nbsp;<span style="font-family: amatic;">>></span>&nbsp;<?php the_tags('tags: ', ', ', '<br />'); ?></p><!-- end post-meta -->
        </div><!-- end post -->
    </div><!-- end preview -->
</div><!-- end blog -->

<?php get_footer(); ?>
  • You call ravs_get_custom_image() with an image's post ID, and then you exclude it in the get_posts() call in ravs_get_custom_image(). Why? (Also, you can double-check your post thumbnail ID with something like echo( 'DEBUG: Thumbnail ID=' . get_post_thumbnail_id() . '<br />' );.)

  • @PatJ Truthfully, I've put all of this together through use of this forum and various tutorials. This is my first attempt at something this complex, and while I am trying to learn along the way it's possible I've missed something. Am I correct in understanding that I should remove 'exclude' => $featured_img from functions.php? (Doing that makes no changes to the site.) Commented May 29, 2013 at 1:36

Since you appear to be using Featured Images, replace this:

<div class="post-image">
    <?php echo ravs_get_custom_image( get_post_thumbnail_id () ); ?>
</div><!-- end post-image -->

with this:

<div class="post-image">
        if ( has_post_thumbnail() ) {
            the_post_thumbnail( 'custom-image' );

    Excellent. Experience has taught me that WordPress handles a lot of this stuff for you, out of the box; sometimes it's just a matter of scrolling through the Codex's Function Reference.
