Zend captcha html
===

I am creating captcha like this using `Zend_Form`:


    class Form_Signup extends Zend_Form {
    
        public function __construct( array $options = null ) {
    
            // set method
            $this->setMethod('post');
            
            // other elements here        
            
            // captcha 
            $captcha = new Zend_Form_Element_Captcha('captcha', array(
                    'id'=>'captcha',
                    'title'=>'Security Check.',
                    'captcha' => array(
                    'captcha' => 'Image',
                    'required' => true,
                    'font'=> 'fonts/ARIALN.TTF',
                    'wordlen'=>'4',
                    'width'=>'200',
                    'height'=>'50',
            		'ImgAlign'=>'left',
            		'DotNoiseLevel'=>'30',
                    'LineNoiseLevel'=>'7', 
                    'Expiration'=>'1000',
                    'fontsize'=>'30',
                    'gcFreq'=>'10',
                    'imgdir'=> 'images/captcha/',
                    'ImgAlt'=>'Captcha',
                    'imgurl'=>'/images/captcha/'
                    )));
            $captcha->removeDecorator('HtmlTag')
            ->removeDecorator('Label')
            ->addDecorator('Label');        
                    
            // add captcha
            $this->addElement( $captcha );          
            $this->setDecorators( array( array( 'ViewScript', array( 'viewScript' => 'signup/signup-form.phtml' ) ) ) );    
        } 
    
    }

It is generating HTML like this:

    <img width="200" height="50" alt="Captcha" src="/images/captcha/cabf4d4d759ae8e4b7404b95e032e231.png">
    <input type="hidden" name="captcha[id]" value="cabf4d4d759ae8e4b7404b95e032e231" title="Security Check." id="captcha">
    <input type="text" name="captcha[input]" id="captcha" value="" title="Security Check.">

**But I want textbox of captcha below the image like this:**

    <img width="200" height="50" alt="Captcha" src="/images/captcha/cabf4d4d759ae8e4b7404b95e032e231.png">
    <br />
    <input type="hidden" name="captcha[id]" value="cabf4d4d759ae8e4b7404b95e032e231" title="Security Check." id="captcha">
    <input type="text" name="captcha[input]" id="captcha" value="" title="Security Check.">


Any idea ?

Thanks
