    copied!<p>You can make the function fb_comment_count call a optional variable, here I will call it $id, which will contains the ID of the attachement (optional so it will not break the function in other areas of site). Then with that ID we can get the attachment page's URL with get_attachment_link, is in that page that we'll find the comments for attachment. The code should be something like:</p> <pre><code>&lt;?php // FB Comment Count (by Zack Austin) // Changes by Bruno Cantuaria (bruno@cantuaria.net.br) function fb_comment_count($link = 'link', $id = 0) { global $post; $url = 'https://graph.facebook.com/'; if ($id &gt; 0) $posturl = get_attachment_link($id); else $posturl = get_permalink($post-&gt;ID); $url .= $posturl; $filecontent = wp_remote_retrieve_body(wp_remote_get($url, array('sslverify'=&gt;false))); $json = json_decode($filecontent); $count = $json-&gt;comments; if ($count == 0 || !isset($count)) { $count = 0; } $comments = $count; if ($count == 1) { $comments .= ''; } elseif ($count == 0) { $comments = '0'; } elseif ($count &gt; 1) { $comments .= ''; } if ($link == 'nolink') { return $comments; } else { return '&lt;a href="'.$posturl.'#comments" title="Comments for '.$post-&gt;post_title.'"&gt;'.$comments.'&lt;/a&gt;'; } } // Custom Gallery add_filter( 'post_gallery', 'my_post_gallery', 10, 2 ); function my_post_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' =&gt; 'ASC', 'orderby' =&gt; 'menu_order ID', 'id' =&gt; $post-&gt;ID, 'itemtag' =&gt; 'dl', 'icontag' =&gt; 'dt', 'captiontag' =&gt; 'dd', 'columns' =&gt; 3, 'size' =&gt; 'thumbnail', 'include' =&gt; '', 'exclude' =&gt; '' ), $attr)); $id = intval($id); if ( 'RAND' == $order ) $orderby = 'none'; if ( !empty($include) ) { $include = preg_replace( '/[^0-9,]+/', '', $include ); $_attachments = get_posts( array('include' =&gt; $include, 'post_status' =&gt; 'inherit', 'post_type' =&gt; 'attachment', 'post_mime_type' =&gt; 'image', 'order' =&gt; $order, 'orderby' =&gt; $orderby) ); $attachments = array(); foreach ( $_attachments as $key =&gt; $val ) { $attachments[$val-&gt;ID] = $_attachments[$key]; } } elseif ( !empty($exclude) ) { $exclude = preg_replace( '/[^0-9,]+/', '', $exclude ); $attachments = get_children( array('post_parent' =&gt; $id, 'exclude' =&gt; $exclude, 'post_status' =&gt; 'inherit', 'post_type' =&gt; 'attachment', 'post_mime_type' =&gt; 'image', 'order' =&gt; $order, 'orderby' =&gt; $orderby) ); } else { $attachments = get_children( array('post_parent' =&gt; $id, 'post_status' =&gt; 'inherit', 'post_type' =&gt; 'attachment', 'post_mime_type' =&gt; 'image', 'order' =&gt; $order, 'orderby' =&gt; $orderby) ); } if ( empty($attachments) ) return ''; if ( is_feed() ) { $output = "\n"; foreach ( $attachments as $att_id =&gt; $attachment ) $output .= wp_get_attachment_link($att_id, $size, true) .
