Filtering search bar for javascript project

Hi guys, I have posted a few questions lately for help on my project. I have been messing around with the javascript coding and still have yet to find a solution to my problem. I need the search bar to filter through the images on the page based off the keywords in the captions. It is supposed to only show images that contain the keywords typed in the search bar, and hide the remaining photos that do not contain the keywords. Here is some of my code...

<form action="" method="post">
      <fieldset>
        <input type="search" id="filter" name="user_search" placeholder="Search(16pt)">
      </fieldset>
    </form>
    <ul class="imageGallery">
      <li><a href="img/fullsize/01.jpg" data-title="I love hay bales. Took this snap on a drive through the countryside past straw fields." data-lightbox="picture_one"><img src="img/thumb/01.jpg" alt=""></a></li>

</ul>
    <script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
    <script src="js/lightbox.js" type="text/javascript"></script>
    <script src="js/main.js" type="text/javascript"></script>
  </body>
</html>

$("#filter").keyup(function(search){
  var $captions = document.querySelectorAll(".imageGallery a");
  var $image = ".imageGallery a";
  if ( search.toLowerCase() === $captions.toLowerCase() ) {
    $image.show();
  } else {
    $image.hide();
  }
});
