Text doesn't start centered when calling jquery's show('slow') and hide('slow')

Question

I'm have a little trouble with this jquery show('slow') and hide('slow'). I have a div, and inside it I have a ajax loading gif that appears when I'm doing some processing, here is a simple example:

       <input type="button" id="btnShow" value="Show"/>
       <input type="button" id="btnHide" value="Hide"/>

       <div id="loading"><img src="~/Content/ajax-loader.gif" /></div>

       <script type="text/javascript">
          $(function () {
              $("#loading").hide();

               $("#btnShow").click(function() {
                  $("#loading").show('slow');
               });
               $("#btnHide").click(function () {
                  $("#loading").hide('slow');
               });
          })
       </script>

      <style type="text/css">
          #loading{
             text-align: center;

          }
      </style>

The problem is, the content should be centered on the div, but when I click on "btnShow" it starts on the left and goes to the middle when it's completely opened... The sam thing happens when I hide it... The loading gif is on the middle and when it's closing it goes to the left... How could I prevent this from happening?

You want the fadeIn and fadeOut functions, not the show and hide. This should do it for you. Just replace the relevant code. =]

$("#btnShow").click(function() {
    $("#loading").fadeIn('slow');
});
$("#btnHide").click(function () {
    $("#loading").fadeOut('slow');
});
