Need a little Redirect help here

I have this Code in an upload request. Upon completion I want to Re-direct to a specific link

How would I write that in here???


 $this->_debugoutput .= JText::_('JGS_ALERT_PICTURE_SUCCESSFULLY_ADDED') . '<br />';
          $this->_debugoutput .= JText::sprintf('JGS_NEW_FILENAME', $newfilename) . '<br /><br />';

          $this->_mainframe->triggerEvent('onAfterJoomUpload', array($row));
        }
      }
      else
      {
        $this->_debugoutput .= JText::_('JGS_ALERT_INVALID_IMAGE_TYPE');
        continue;
      }
    }

    echo $this->_debugoutput;

    JHTML::addIncludePath(JPATH_COMPONENT.DS.'helpers'.DS.'html');

header(‘Location: http://blah.com/page’);
