    $form->setMethod('post'); 
    $form->setAttrib('enctype', 'multipart/form-data'); 
    $form->setAttrib('sitename', 'hostname'); 

    $logo = new Zend_Form_Element_File('logo'); 
    $logo->setDecorators(array('File', 
      array(array('data'=>'HtmlTag'), array('tag' => 'td')), 
      array('Label', array('tag' => 'td')), 
      array(array('row'=>'HtmlTag'),array('tag'=>'tr'))
