Using jQuery.noConflict, you can make multiple versions of jQuery coexist on the same page, all you need to do is declare the Jquery variable for that version like this…
<script src='jquery-1.3.2.js'></script>
<script>
var $jq132 = jQuery.noConflict();
</script>
<script src='jquery-1.4.2.js'></script>
<script>
var $jq142 = jQuery.noConflict();
</script>
And then replace in your Jquery code like this…
window.onload = function () {
var container = $jq142('div.sliderGallery');
Simple!
