title: Preloaded images cause hard-coded image to disappear on leaving a page
body: <p>I have a slideshow (more like a fadeshow actually) set up with jQuery. Initially, the hard-coded image is displayed, and I preload the remaining images from an array of sources with:</p>
  
  <pre><code>function preload(imgArray) {
      $.each(imgArray, function() {
          $.get(this);
      });
  }
  </code></pre>
  
  <p>This all works fine. However, if I navigate away from the page within the first few seconds of arriving (while preloaded images are still being downloaded, but well after the initial image has fully loaded), the original hard-coded image disappears and the red X (normally shown when an image isn't found) shows up. (only noticed in FF 23 on Windows 7 SP1)</p>
  
  <p>I have never noticed it before working on this particular site. It isn't a problem, since I'm leaving the page anyway, but why does this happen? Does it have anything to do with my code, or is this standard browser behavior while a resource download is interrupted?</p>
