On single.php theme template file, I'm displaying the post's list of attachments.

global $post;
$args = array(
    'post_type' => 'attachment',
    'numberposts' => null,
    'post_status' => null,
    'post_parent' => $o_ID
$attachments = get_posts($args);
if ($attachments) {
    echo '<ul class="slideshow-controller">';
    foreach ($attachments as $attachment) {
        //echo apply_filters('the_title', $attachment->post_title);
        echo '<li>';
        echo wp_get_attachment_link($attachment->ID, 'thumbnail', 0, 0, 'Download');
        echo wp_get_attachment_image($attachment->ID, 'thumbnail',false);
        echo '</li>';
    echo '</ul>';

Weird, wp_get_attachment_linkworks correctly (echoes the attachment's media link), wp_get_attachment_imagedoes not: it echoes nothing at all.

What am i doing wrong?

where and how is $oID defined? – iEmanuele Aug 28 '13 at 11:47
Just try removing 'numberposts' => null parameter from get_posts() function array $args – Vinod Dalvi Aug 28 '13 at 12:35

Replace the line

echo wp_get_attachment_image($attachment->ID, 'thumbnail',false);


echo $attachments['post_content'];

Thank you, but that does not solve the issue: false refers to the use of the media icon, which is false by default. – pixeline Aug 28 '13 at 11:25
I have edited my answer, please try the above code. – user930026 Aug 28 '13 at 11:39
$attachments is an array. – s_ha_dum Aug 28 '13 at 11:58
