Adding Captions to a Dynamic Featured Slider

Hello,

I’m using the code below to show the featued image & the dynamic featured image in a slider on my homepage & post pages.

<?php if( class_exists('Dynamic_Featured_Image') ) {
     global $dynamic_featured_image;
     $featuredImages = $dynamic_featured_image->get_featured_images( $postId );

    if( !is_null($featuredImages) ){
       echo "<div class='entry-thumbnail nivoSlider'>";
	   if (has_post_thumbnail( $post_id ) ){?>
       <a href="<?php get_permalink();  ?>" class="thickbox"><img alt="thumb image" class="wp-post-image" src="<?php $image_id = get_post_thumbnail_id(); $image_url = wp_get_attachment_image_src($image_id,'header_news_thumb', true); echo $image_url[0];  ?>"></a>
	   <?php }
       foreach($featuredImages as $images) {
           echo "<a href='" . get_permalink() . "' title = '" . $dynamic_featured_image->get_image_alt_by_id($images['attachment_id']) . "' class='thickbox'>";
           echo "<img src='" . $images['full'] . "' />";
           echo "</a>";                                          
       }
       echo "</div>";
    } 
 } ?>

Is there a way to add captions with the images to the code. No matter what I try it does the first image, but not the rest. It also then screws with the image sizes after that.

Any help would be great.

Thanks
Wayne
