title: Rails 4 & JQuery UI datepicker - icon not showing up
body: <p>I'm using the date picker widget from JQuery UI in my Rails 4 app. The date picker is working as expected except that the calendar image is not showing up. </p>
  
  <p>I guess my questions are... </p>
  
  <ol>
  <li>What is the proper directory to store the 'calendar.png' file that will be used in buttonImage?</li>
  <li>And then, what path should I use in 'buttonImage: "path"</li>
  </ol>
  
  <p>The file (calendar.png) is currently saved in assets/images and have tried it in various other directories and various paths with no luck. The view always shows the missing image icon. I'm new to the asset pipeline.</p>
  
  <p>Here is the view code:</p>
  
  <pre><code>&lt;div class="form-group"&gt;
    &lt;%= f.label :Date %&gt;:
    &lt;%= f.text_field :requested_from, id: 'datepicker' %&gt;
    &lt;%= f.hidden_field :requested_from, id: 'requested-from-alt' %&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And here is the javascript:</p>
  
  <pre><code>&lt;script&gt;
   $(function(){
    $('#datepicker').datepicker({
  
      dateFormat: "DD, MM d, yy",
  
      showOn: "button",
      buttonImage: "?????????",
      buttonImageOnly: true,
      buttonText: "Select a date",
  
      numberOfMonths: 2,
      altField: "#requested-from-alt",
      altFormat: "yy-mm-dd",
      minDate: '0',
      maxDate: '+1y',
     });
    });
  &lt;/script&gt;
  </code></pre>
  
  <p>Thanks!</p>
