Jquery滑块插件，一切正常，但图像不会改变

Question

新查询和我正在使用这个滑块插件，我已经让它手动工作，但参数设置为'interval：true'和'intervalTime：100'，它不会更改图片自动。为什么会这样？

CSS

#rotatescroll { height:300px; position:relative; width:300px; }

#rotatescroll .dot span { display: none; }

Jquery的

$(document).ready(function()
        {
            $('#rotatescroll').tinycircleslider({ interval: true, intervalTime: 100, dotsSnap: true });
        });
