Default Gallery Edit/Template Editable?

1 Views

I quite like the default WordPress Gallery, but i dont like how it plonks the images as thumbnails, with a link to the larger image.

Is there anyway to make it display the images not in a thumbnail link, just as either the full size image or one chosen from the media uploader?

Also in a an li list?

So simply looks like the following.. 

<ul>
  <li><img src="wp-uploads/image.jpg" alt="image" /></li>
  <li><img src="wp-uploads/image.jpg" alt="image" /></li>
</ul>

Or no chance and tough, thats how the gallery works?

Thanks for any advice 🙂

  1. Put this code in your functions.php and check.

    function custom_gallery( $output, $attr ){
    global $post, $wp_locale;

    static $instance = 0;
$instance++;

// We're trusting author input, so let's at least make sure it looks like a valid orderby statement
if ( isset( $attr['orderby'] ) ) {
    $attr['orderby'] = sanitize_sql_orderby( $attr['orderby'] );
    if ( !$attr['orderby'] )
        unset( $attr['orderby'] );
}

extract(shortcode_atts(array(
    'order'      => 'ASC',
    'orderby'    => 'menu_order ID',
    'id'         => $post->ID,
    'itemtag'    => 'li',
    'icontag'    => '',
    'captiontag' => '',
    'columns'    => 3,
    'size'       => 'full',
    'include'    => '',
    'exclude'    => ''
), $attr));

$id = intval($id);
if ( 'RAND' == $order )
    $orderby = 'none';

if ( !empty($include) ) {
    $include = preg_replace( '/[^0-9,]+/', '', $include );
    $_attachments = get_posts( array('include' => $include, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );

    $attachments = array();
    foreach ( $_attachments as $key => $val ) {
        $attachments[$val->ID] = $_attachments[$key];
    }
} elseif ( !empty($exclude) ) {
    $exclude = preg_replace( '/[^0-9,]+/', '', $exclude );
    $attachments = get_children( array('post_parent' => $id, 'exclude' => $exclude, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );
} else {
    $attachments = get_children( array('post_parent' => $id, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );
}

if ( empty($attachments) )
    return '';

if ( is_feed() ) {
    $output = "n";
    foreach ( $attachments as $att_id => $attachment )
        $output .= wp_get_attachment_link($att_id, $size, true) . "n";
    return $output;
}

$itemtag = tag_escape($itemtag);
$captiontag = tag_escape($captiontag);
$columns = intval($columns);
$itemwidth = $columns > 0 ? floor(100/$columns) : 100;
$float = is_rtl() ? 'right' : 'left';

$selector = "gallery-{$instance}";

$gallery_div = '';
$size_class = sanitize_html_class( $size );
$gallery_div = "<ul id="$selector" class="gallery galleryid-{$id} gallery-columns-{$columns} gallery-size-{$size_class}">";
$output = apply_filters( 'gallery_style', $gallery_div );

$i = 0;
foreach ( $attachments as $id => $attachment ) {
    $image = wp_get_attachment_image( $id, $size );

    $output .= "<{$itemtag} class="gallery-item">";
    $output .= $image;
    if ( $captiontag && trim($attachment->post_excerpt) ) {
        $output .= "
            <{$captiontag} class="wp-caption-text gallery-caption">
            " . wptexturize($attachment->post_excerpt) . "
            </{$captiontag}>";
    }
    $output .= "</{$itemtag}>";
}

$output .= "
    </ul>n";

return $output;
}
add_filter('post_gallery', 'custom_gallery', 11, 2);

    This will output the uploaded image as it is instead of the thumbnail in a list.
