how can i achieve that? thanks a lot!

You want to use the position: fixed CSS property with top: 0; right: 0.

If you need IE 6 support, check this page.

$("#triggerId").mouseover(function (e) {
    $("#cornerImageId").show();
});

And have in your CSS:

#cornerImageId {
    position: fixed;
    top: 0;
    right: 0;
}

$(function(){
  $("#certain_element").mouseover(function(){
    $("#certain_img").css({position:"fixed",right:"0px",top:"0px"});
  });
});
