put image as hidden,

$(window).scroll(function() {
   if($(window).scrollTop() + $(window).height() == $(document).height()) {
   $('img').show().animate();

} });

try smth like this:

   if ($(window).scrollTop() >= "250") $('#your_div').fadeIn("slow");

it means that if you lower than 249 from the top you will gain the button

     $('#your_div').click(function () {
        $('body,html').animate({
            scrollTop: 0
        }, 300);
        return false;
    });

so after you click it you will go up through 0,3 sec.

Use ScrollTop() function in jquery

Call this function in image onclick

onclick="$('body').scrollTop();"

See Demo
