In the image slider the output of the image as <img> tag:

<?php
$f = File::getByID($row['fID'])
     if (is_object($f)) {
          $tag = Core::make('html/image', array($f, false))->getTag();
              if ($row['title']) {
                   $tag->alt($row['title']);
              } else {
                   $tag->alt("slide");
         }
           echo $tag;
?>
