模板列里加入一个Image控件，然后ItemDataBound事件里加

protected void Repeater2_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        for (int i = 0; i <Repeater2.Items.Count; i++)
        {
            if (i<3)
            {
             
                if (Request["page"]==null || Request["page"]=="1") //因为做了分页,这里判断下是否是第一页
                {
                    ((Image)Repeater2.Items[i].FindControl("Image1")).Visible = true;
                }
               
            }
        }
    }
