I have done a sample using jquery, that works.
<script language="javascript" type="text/javascript" >
$().ready(function () {
//alert("I am in the ready");
//alert($("img").length);
$("img").mouseover(function () { $(this).width(200); $(this).height(200) });
$("img").mouseleave(function () { $(this).width(50); $(this).height(50) });
})
</script>
Use a better selectors for finding only our specific images in the grid view.
The above code should trick on mouse over image resizing.
