SharePoint with jQuery Help Needed

SharePoint with jQuery Help Needed

The following jQuery works great in SharePoint 2007 with a Content Editor Web Part.  It makes the icons bigger on one site as they use the document library on touch screens on a factory floor.  After upgrading to 2010, the folder icon still works, the PDF icon does not.  The files are in place.  I can go to the path manually and bring up the icon image.  Not sure what changed to stop it from working.

<script src="/usm/Dandridge/Application%20Files/jquery.min.js" type="text/javascript"></script>

<script type="text/javascript">

$(document).ready(function(){

$("td.ms-vb-icon a img[src*='folder']").each(function(){
           $(this).attr("src", "/_layouts/images/fldrnew.gif");   //set this value to the bigger folder icon
});

$("td.ms-vb-icon a img[src*='pdf']").each(function(){
           $(this).attr("src", "/_layouts/images/pdf-big.png");   //set this value to the bigger PDF icon
});

});</script>
