title: ruby array, get all elements from second to last
body: <p>My method:</p>
  
  <pre><code> def scroll_images
     images_all[1..images_all.length]
   end
  </code></pre>
  
  <p>I don't like that I'm calling <code>images_all</code> twice, just wondering if there's a good trick to call <code>self</code> or something similar to make this a little cleaner. </p>
