[development] Altering links

[Carl Wiedemann]

You could achieve it with both CSS and preprocess by doing something like
this:

In your template.php file, mytheme_preprocess_node():

// START
$node = $vars['node'];

if (!empty($node->links['comment_comments'])) {
  // Class depending on node comment count.
  if (!empty($node->comment_count)) {
    $myclass = 'has-comments';
  }
  else {
    $myclass = 'no-comments';
  }

  // Add to particular link class.
  if (empty($node->links['comment_comments']['attributes']['class'])) {
    $node->links['comment_comments']['attributes']['class'] = $myclass;
  }
  else {
    $node->links['comment_comments']['attributes']['class'] .= ' ' .
$myclass;
  }

  // Reformat all links
  $vars['links'] = !empty($node->links) ? theme('links', $node->links,
array('class' => 'links inline')) : '';
}
// END


In your theme's css file

/* START */
.has-comments {
  backgorund-image: url(./images/some-image.png);
  background-repeat: none;
  padding-left: 2em;
}

.no-comments {
  background-image: none;
  padding-left: 0;
}
/* END */
