So, i got this code to retrieve the images inserted in a gallery within a post:

$args = array(
    'post_type' => 'attachment',
    'numberposts' => -1,
    'post_mime_type' => 'image',
    'post_parent' => $post->ID,
    'orderby' => 'menu_order',
    'order' => 'ASC'
$attachments = get_posts($args);
if ($attachments) {
    foreach ($attachments as $attachment) {
        $image_attributes = wp_get_attachment_image_src( $attachment->ID, 'full' );
        ?><img title="<?php echo $attachment->post_title; ?>" src="<?php echo $image_attributes[0] ?>" /><?php

and the output if fine, except that some pictures are duplicated and given a class="cloned" attribute.

This code is running within a basic loop:

<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>

with no extra special things before and after. This is happening locally and online as i wanted to be sure about this weird thing; here's the demo. If you inspect the code you'll see this:

<img class="cloned" src="http://k-win.fr/wptest/wp-content/uploads/2011/06/03mopi.jpg" title="03mopi">
<img src="http://k-win.fr/wptest/wp-content/uploads/2011/06/01.jpg" title="01">
<img src="http://k-win.fr/wptest/wp-content/uploads/2011/06/02.jpg" title="02">
<img src="http://k-win.fr/wptest/wp-content/uploads/2011/06/03mopi.jpg" title="03mopi">
<img class="cloned" src="http://k-win.fr/wptest/wp-content/uploads/2011/06/01.jpg" title="01">

But if you check the source code you wont see the class="cloned" i'm speaking of (devil inside!).

It's driving me a bit crazy cos it's messing up with the pictures order in some cases and this one has to be respected from the order decided in the gallery's options.

I checked with Opera, Chrome and Firefox, and all show me the same thing. Any clue?

that's your nivo-slider at work

  • True, it wasn't wordpress but the slider, which was not nivo but another one. I changed it and got it all working fine at last. Thanks a lot Piet.
