$(document).ready(function() {

/* $("a[rel^='prettyPhoto']").prettyPhoto(); */
$("a[rel^='prettyPhoto']").prettyPhoto({ social_tools: false, theme: 'light_rounded' });
});

 
$(document).ready(function () {
$("a[rel^='prettyPhoto']").prettyPhoto(
callback: function() {
location.href = location.href + '#tab-2';
/* window.location.reload(true); */
}
);
});
