title: Change the size of the captcha image in yii
body: <p>I would like to change the size of the captcha image in yii. I know the width originally is set to 100. I would like to make it twice as big. I can't get anything to change with the following code.   </p>
  
  <pre><code>&lt;?php $this-&gt;widget('CCaptcha',array('buttonOptions'=&gt;array('style'=&gt;'width:200'))); 
  </code></pre>
