title: How do you append images that are already created with appendImage?
body: <p>The php website lists the following <a href="http://us2.php.net/manual/en/function.imagick-appendimages.php" rel="nofollow">example</a>:</p>
  
  <pre><code> &lt;?php
  
  /* Create new imagick object */
  $im = new Imagick();
  
  /* create red, green and blue images */
  $im-&gt;newImage(100, 50, "red");
  $im-&gt;newImage(100, 50, "green");
  $im-&gt;newImage(100, 50, "blue");
  
  /* Append the images into one */
  $im-&gt;resetIterator();
  $combined = $im-&gt;appendImages(true);
  
  /* Output the image */
  $combined-&gt;setImageFormat("png");
  header("Content-Type: image/png");
  echo $combined;
  ?&gt;
  </code></pre>
  
  <p>How do I use an image generated from a URL instead, such as </p>
  
  <pre><code>$image = new Imagick("sampleImage.jpg");
  </code></pre>
  
  <p>so that I could append the loaded images instead of using <code>newImage()</code></p>
