Hide image if src is empty

Question

I'm trying to hide <img> if the source is empty. But I have no luck.

I found few posts here, but it doesn't work for me.

Here is my code, it's table based because it will be a template: Images:

<td width="92%" align="center" class="imagenes_desc">
        <a href="#" class="showcase"><img class="imagen" src="http://webs.ono.com/norfolk/ebay/images/01.jpg" width="800"></a>
        <a href="#" class="showcase"><img class="imagen" src="" width="800"></a>
        <a href="#" class="showcase"><img class="imagen" src="" width="800"></a>
        <a href="#" class="showcase"><img class="imagen" src="" width="800"></a>
        <a href="#" class="showcase"><img class="imagen" src="" width="800"></a>
        <a href="#" class="showcase"><img class="imagen" src="" width="800"></a>
        <a href="#" class="showcase"><img class="imagen" src="" width="800"></a>
        <a href="#" class="showcase"><img class="imagen" src="" width="800"></a>
        <a href="#" class="showcase"><img class="imagen" src="" width="800"></a>
        <a href="#" class="showcase"><img class="imagen" src="" width="800"></a>
        </td>

Here is the Javascript I'm trying to implement.

<script type="text/javascript">
        $(document).ready(function(){
            if ($(".imagen").attr(src="") == "") {
                $(".imagen").hide();
            }
            else {
                $(".imagen").show();
            }
</script>

I'm not very familiar with JS, I found this script here on Stackoverflow, but I can't get it to work.

Update

Trying this, but doesn't work (Chrome hides well, but Firefox and IE don't):

<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js'></script>
<script type="text/javascript">
$("imagen").each(function(){

  if ($(this).attr("src") == "") 
       $(this).hide();
  else

      $(this).show();
});
</script>
<style>
.hide {display:none !important;}
.show {display:block !important;}
</style>

Thanks,

You can just use CSS for this:

img[src=""] {
    display: none;
}

<img src="">
<img src="http://dreamatico.com/data_images/kitten/kitten-2.jpg">

How about using jQuery's attribute selectors?

    $(document).ready(function(){
        $('.imagen[src=""]').hide();
        $('.imagen:not([src=""])').show();
    });
