      {
            height: 150px;
            width: 150px;

Step 3: Add below jquery in the page.

<script type="text/javascript">
      $(function() {
            $("img.imgThNail").mouseover(function(e) {
                  var newImg = '<img src=' + $(this).attr("src") + '></img>';
                  $('#sourceDiv')
                        .html($(newImg)
                        .animate({ height: $(this).width() + 40, width: ($(this).width() + 40) }, 10));
            var left = ($(this).position().left - 20) + "px";
            var top = ($(this).position().top - 20) + "px";
            $("#sourceDiv").css({
                  position: 'absolute',

                  left: left,
                  top: top,
                  display: 'block'

            $("#sourceDiv").css({
                  display: 'none'
                  });
            });
