 * Hi there,
 * I want to display the ‘recent comments’ in wp-carousel.
 * `<ol class="commentlist"><?php wp_list_comments(array('style' => 'ol')); ?></
   ol>`
 * The ‘costumized content’ widget does not execute this php.
 * Any ideas for executing php code within the WP-Carousel greatly appreciated!
 * Regards,
 * Jim C.

 * Hello,
 * I had a similar problem with posts. I wanted to show the number of published 
   posts in a post and I wanted this number to be updated every time I publish a
   new post. The solution was to use a keyword (something like, for instance, [LAST_COMMENTS])
   and replace that keyword later with filters and actions.
 * But with WP Carousel you have it easier. First, select a keyword, for instance,[
   LAST_COMMENTS]. Then modify your WP Carousel’s theme and replace this line:
 *     ```
       <?php foreach ($items as $i_id => $item): ?>
       ```
   
 * With these three lines:
 *     ```
       <?php foreach ($items as $i_id => $item): ?>
       <?php $replacement = '<ol class="commentlist">'.wp_list_comments(array('style' => 'ol')).'</ol>'; ?>
       <?php str_replace('[LAST_COMMENTS]', $replacement, $item['DESC']); ?>
       ```
   
 * The only problem you will get is that wp_list_comments prints by default the 
   comments (instead of returning them), so you need to set a callback function 
   to return the content in order to allow the variable $replacement to store the
   comments. You have more info about this in the codex.
