title: Magento: How to enable/disable module output per website level?
body: <p>I would like to <strong>display an image in the onepage checkout payment methods section that would only show up in one of two website levels</strong>. So I have three questions:</p>
  
  <p><strong>1)</strong> Am I correct to assume this change would be coded in app/design/frontend/default/mytheme/layout/checkout.xml ?</p>
  
  <p><strong>2)</strong> if that is the correct file, what would the change be from:</p>
  
  <pre><code>&lt;!--
  One page checkout payment methods block
  --&gt;
      &lt;checkout_onepage_paymentmethod&gt;
          &lt;remove name="left"/&gt;
  
          &lt;block type="checkout/onepage_payment_methods" name="root" output="toHtml" template="checkout/onepage/payment/methods.phtml"&gt;
              &lt;action method="setMethodFormTemplate"&gt;&lt;method&gt;purchaseorder&lt;/method&gt;&lt;template&gt;payment/form/purchaseorder.phtml&lt;/template&gt;&lt;/action&gt;
          &lt;/block&gt;
      &lt;/checkout_onepage_paymentmethod&gt;
  </code></pre>
  
  <p>in order to point to, for example, checkout/onepage/payment/methods-site2.phtml when site2 is being used?</p>
  
  <p><strong>3)</strong> Is this the proper way to do this in 1.5.x ?</p>
