I have to right click blocks for the stolen photos eliminate in my website, but I would also block the left click, because a lot of clicking with the left into the photo and drag the photos and steal.Can anyone tell me how to edit here in the script that I can block the left click..<script language=JavaScript>

    var message = "Function Disabled!";

    function clickIE4() {

        if (event.button == 2) {

            alert(message);

            return false;

        }

    }

    function clickNS4(e) {

        if (document.layers || document.getElementById && !document.all) {

            if (e.which == 2 || e.which == 3) {

                alert(message);

                return false;

            }

        }

    }

    if (document.layers) {

        document.captureEvents(Event.MOUSEDOWN);

        document.onmousedown = clickNS4;

    } else if (document.all && !document.getElementById) {

        document.onmousedown = clickIE4;

    }

    document.oncontextmenu = new Function("alert(message);return false")

</script>

Thank you!
