[jQuery] g has no properties?

I am doing a simple imageChange onLinkHover...

I get the following error in Firebug everytime I hover over a link.
But the image swaps work GREAT in all browsers.
Except for the fact I see the error getting thrown in the browsers I
am fine.

The jQuery code to swap images is:

        $(".showPic").hover(function() {
                $("#imgLinkAct").attr("src", "images/cylinder.jpg");
        });
        $(".showPic2").hover(function() {
                $("#imgLinkAct").attr("src", "images/mgp_swap.jpg");
        });
        $(".showPic3").hover(function() {
                $("#imgLinkAct").attr("src", "images/mhc_swap.jpg");
        });
        $(".showPic4").hover(function() {
                $("#imgLinkAct").attr("src", "images/shock_swap.jpg");
        });
        $(".showPic5").hover(function() {
                $("#imgLinkAct").attr("src", "images/emy2_swap.jpg");
        });
        $(".showPic6").hover(function() {
                $("#imgLinkAct").attr("src", "images/ncy2_swap.jpg");
        });
        $(".showPic7").hover(function() {
                $("#imgLinkAct").attr("src", "images/crq_swap.jpg");
        });
        $(".showPic8").hover(function() {
                $("#imgLinkAct").attr("src", "images/clean_room_swap.jpg");
        });

});
