Like that doesn\'t

Answer 1

I feel This is easier to read and navigate...

      $sub = $this->select()
            ->setIntegrityCheck(false)
            ->from(array('i' => 'images'), array('*'))
            ->order('i.image_id');

$select = $this->select()
             ->setIntegrityCheck(false)
             ->from(array('m' => 'MAIN_TABLE'), array('*'))
             ->joinRight(array('i' => $sub), 'i.ad_id = m.id', array('*'));

   return $this->select($select);

Answer 2

Use

$select->joinRight(
    array('i' => new Zend_Db_Expr('(SELECT * FROM images ORDER BY image_id)')),
    'i.ad_id = '. $main .'.id',
    $imarray
);
