title: ImageMagick: How to combine 200 images in pairs of 2 side-by-side (book layout)
body: <p>I have 200 jpgs that are the same size. I need to combine them in pairs, putting them side-by-side.</p>
  
  <p>So</p>
  
  <pre><code>1.jpg
  2.jpg
  3.jpg
  4.jpg
  </code></pre>
  
  <p>Should make 2 new jpgs, one containing 1 and 2, and the other containing 3 and 4. Side by side.</p>
  
  <p>Think of each image as a page of a book.</p>
  
  <p>Is there anyway to automate this using imageMagick montage?</p>
