title: No arrow on images when using bxslider
body: <p>I just learnt about bxslider and made my first slideshow by reading the docs. But <strong>I cant see the right and left arrows on the images so that the next image can be shown by a click</strong> as shown in this example at: <a href="http://bxslider.com/examples/image-slideshow-captions" rel="nofollow noreferrer">This Link</a></p>
  
  <p>Here is my code: </p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;New seven Wonders of the world&lt;/title&gt;
  &lt;script type="text/javascript" src="jquery.js"&gt;&lt;/script&gt;
  &lt;script src="jquery.bxslider.min.js"&gt;&lt;/script&gt;
  &lt;!-- bxSlider CSS file --&gt;
  &lt;link href="jquery.bxslider.css" rel="stylesheet" /&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;ul class="bxslider"&gt;
    &lt;li&gt;&lt;img src="pic2.jpg" title="Great Wall of China, China"/&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="pic3.jpg" title="Petra, Jordan" /&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="pic4.jpg" title="Colosseum, Rome, Italy" /&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="pic5.jpg" title="Chichen Itza, Mexico" /&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="pic6.jpg" title="Machu Pichu, Peru" /&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="pic7.jpg" title="Taj Mahal, India" /&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="pic8.jpg" title="Christ the redeemer, Brazil" /&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="pic1.jpg" title="Giza Necropolis, Egypt (Honorary title only)" /&gt;&lt;/li&gt;
  &lt;/ul&gt;
  &lt;script type="text/javascript"&gt;
  $(document).ready(function(){
    $('.bxslider').bxSlider({slideWidth: 700,auto: true,
    mode: 'fade', captions: true, speed: 700});
  });
  &lt;/script&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Any reason why I can't see those 2 arrows which, when clicked, give the next or previous slide? I couldn't really find out anything different that I may have written or anything that I may have forgot.</p>
