Problem with hover function

Problem with hover function

My problem can be viewed here:

When I hover my mouse away from the project image (over the title), things get buggy. I know why it happens, I just don't know how to fix it.

here is the code I am using for this part:

  1.     /**
         * Display the project title when
         * mouse is hovered over corresponding
         * gallery image. (useless, but cool)
         */
        function displayTitle() {
            var img = $('img.gallery-img');
            img.hover(function() {
                var p = $(this).position();
                $(this).siblings().css({
                    'top': p.top,
                    'left': p.left
                });
                $(this).siblings().show();
            }, function() {
                $(this).siblings().hide();
            });
        }
