Need help with slider shortcode.

What i want to use is slider from Foundation 5 framework (Orbit) as shortcode. You can see how it’s work here : http://foundation.zurb.com/docs/components/orbit.html

So far i found some code and after edits got this and it’s working great displaying images.

add_shortcode('orbit', 'orbit_function');
function orbit_function($atts){
   extract(shortcode_atts(array(
      'ids' => '',
      'size' => 'full',
   ), $atts));

$arr= explode(",",$ids); //prints an array of numbers

echo "<ul id=\"container\" class='example-orbit' data-orbit>\n";
foreach($arr as $id) {
  $img = wp_get_attachment_image_src($id, $size);
  echo "<li><img src=\"$img[0]\"></li>\n";
}
  echo "</ul>\n";
}

Now how can i display image caption in orbit ( <div class=”orbit-caption”> caption </div>) and if possible image description as content ( <div> description </div> ) like on orbit docs.
