title: paypal express checkout change image button
body: <p>I am using the advanced integration procedure to integrate a paypal button, but I would like to change the default image of the button with the one that includes also the credit card logos, e.g.: </p>
  
  <pre><code>&lt;script src="https://www.paypalobjects.com/api/checkout.js"&gt;&lt;/script&gt;
  
  &lt;div id="paypal-button"&gt;&lt;/div&gt;
  
  &lt;script&gt;
    paypal.Button.render({
      env: 'sandbox',
      locale:'it_IT',
      payment: function(resolve, reject) {
           var CREATE_PAYMENT_URL = '/make-payment';
  
          paypal.request.post(CREATE_PAYMENT_URL)
              .then(function(data) { resolve(data.paymentID); })
              .catch(function(err) { reject(err); });
      },
      style: {
          size: 'medium',
          color: 'blue',
          shape: 'rect'
      },
      onAuthorize: function(data, actions) {
          console.log("done")
     }
  }, '#paypal-button'); 
  &lt;/script&gt;
  </code></pre>
  
  <p>By reading the documentation it seems that it is not possible to set an attribute to change the default paypal image. Any ideas?</p>
