   Hi,

   I have a post type with a meta-box that lists all images in the gallery for that post. What I would like to do, is update that list when a new image gets uploaded to the gallery. I was hoping for an action hook that gets triggered after uploading an image, so I could then trigger my function to update the gallery list. But somehow I can't get it to work.

   this is what's in my functions.php:
   

   add_action('add_attachment', 'update_project_images');
   
            function update_project_images()
            {
                ?>
                   <script type='text/javascript'>
                        jQuery('#images-meta .inside').html("<?=getAttachments()?>");
                    </script>
                <?php
            }
   function getAttachments()
            {
                global $post;
   
                $attachments = & get_children('post_type=attachment&post_mime_type=image&post_parent=' . $post->ID );
   
                if($attachments) {
   
                   // Get array keys representing attached image numbers
                   $arrKeys = array_keys($attachments);
   
                   foreach($arrKeys as $iNum)
                   {
                       // Get the thumbnail url for the attachment
                       $sThumbUrl = wp_get_attachment_thumb_url($iNum);
                       $sImgString = "<img src='" . $sThumbUrl . "' width='100' height='100' \/><br />";
                       echo $sImgString;
                   }
   
                }
            }

   Any ideas?
