.link {
    position: relative;
}
.link span {
    position: absolute;
}

<a class="link" href="http://cnn.com">
    <imgsrc="http://placehold.it/150x100"data-big=""data-title="test title"data-description="test description"/><spandata-url="http://npr.org">Other link</span>

$('.link span').click(function (e) {

    window.location = $(this).attr('data-url');
});
