[SOLVED] JQuery JCaroullite Bug

I use Jquery JCaroullite, but when i slide the image, one of image is disappear, to solve this:

Change the code of javascript on the web page from

$(document).ready(function() { 
$(".jCarouselLite").jCarouselLite({
 btnNext: ".next",
 btnPrev: ".prev",  
 speed: 400,  
 vertical: false,
 circular: true,
 easing:'easeOutQuart',
 visible: 4,
 start: 0,
 scroll: 1
});
});

To

$(document).ready(function() { 
$(".jCarouselLite").jCarouselLite({
 btnNext: ".next",
 btnPrev: ".prev",  
 speed: 400,  
 vertical: false,
 circular: true,
 easing:'easeOutQuart',
 visible: ($("#carousel li img").length>1)?3:2,
 start: 0,
 scroll: 1
});

});
