title: Get a sequence of images into an array
body: <p>I was wondering if it's possible to get a sequence of pictures into an array. I'd like to use plain JavaScript, because I have zero experience in PHP or any other language to achieve this.</p>
  
  <p>So I created a map called "images", which contains 50 images. The first one is called: "1", the second one is called: "2" and so on. They all are the same type (.jpg). </p>
  
  <p>I can do this manually like:</p>
  
  <pre><code>var pictures = new Array();
  pictures[0] = "images/1.jpg";
  pictures[1] = "images/2.jpg";
  //and so on
  </code></pre>
  
  <p>But only a mad man would do this. also when I upload a new picture to the "images" folder, I have to manually add the new image to the array, so I was thinking about a while loop which checks if each image in the folder is stored into the array.</p>
