[Plugin: List category posts] Using lightbox2 with featured image thumbnails

I’ve been on what has turned into a crusade tonight trying to figure out how to make my post thumbnails open in a lightbox as an image and not the actual post(it actually doesn’t load the post, but attempts). After many failed attempts I figured I’d try to replace the post url with a custom value from my custom field. I found later that if I want to use a custom field I need to specify both the name and value. However I’m trying to have the lightbox open a unique image via the custom fields.

I’ve been trying to work with replacing the “get_permalink($single->ID)” with something that is more controllable and that’s an image and not a post.

public function get_thumbnail($single, $lcp_thumb_class = null){
        if ($this->params['thumbnail']=='yes'){
            $lcp_thumbnail = '';
            if ( has_post_thumbnail($single->ID) ) {

              if ( in_array( $this->params['thumbnail_size'], array('thumbnail', 'medium', 'large', 'full') ) ) :
                $lcp_thumb_size = $this->params['thumbnail_size'];
              elseif ($this->params['thumbnail_size']):
                $lcp_thumb_size = explode(",", $this->params['thumbnail_size']);
              else :
                $lcp_thumb_size = 'thumbnail';
              endif;//thumbnail size

              $lcp_thumbnail = '<a rel="lightbxox" href="' . get_permalink($single->ID).'">'; 

              $lcp_thumbnail .= get_the_post_thumbnail(
                                  $single->ID,
                                  $lcp_thumb_size,
                                  ($lcp_thumb_class != null) ? array('class' => $lcp_thumb_class ) : null
                                );
              $lcp_thumbnail .= '</a>';

            }
            return $lcp_thumbnail;
        } else {
            return null;
        }
    }

Any assistance would be greatly appreciated. I hope someone else has attempted this and succeeded!! 🙂
