   I have a slider in my theme running, it basically pulls Featured Images. I would like to be able to add a custom URL to each Featured Image via a Custom Fields that I have created called "slide_url". Anyone has an idea how to make this work? Thanks!

   This is my code in Functions.php:
   

   <?php function get_custom_field_value($szKey, $bPrint = false) {
   	global $post;
   	$szValue = get_post_meta($post->ID, $szKey, true);
   	if ( $bPrint == false ) return $szValue; else echo $szValue;
   }
   ?>

   This is my modified code which is not working at the moment:

   <?php
   $values = get_post_custom_values('slide_url');
   if (isset($values[0])) {
       echo '<a href="'.get_permalink().'" ><img src="'.$values[0].'" alt="'.get_the_title().'" /></a>';
   } elseif ( has_post_thumbnail() ) {
      $large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'large');
      echo '<a href="' . $large_image_url[0] . '" title="' . the_title_attribute('echo=0') . '" >';
      the_post_thumbnail('blogbig');
      echo '</a>';
    } ?>

   The featured image 'blogbig' in your slider has the link to the large image. In this example custom image has the link to the post url get_permalink(). To make it work as slider image you need second custom field image like 'slide_url_large' )))
