Javascript IE不从js加载图像

我的问题仅在IE中显示，并且仅当我第一次连接时，当我刷新页面时，图像才会显示！！！ 我的页面是用jQuery脚本在顶部构建的，之后是html

        <div id="statusbar" >
        <img class="statusbar_phone" />
        <img class="statusbar_text"  />
        <img class="arrow" style="display:none" src="//expertsimages.liveperson.com/images/phonewidget/arrow_up.png" />
    </div>

任何建议：

你能为此创建一个提琴吗？图像源属性中的“//”是什么意思？@reporter，这样你就不需要http://或https://... 它将以与当前相同的协议继续@免费的谢谢。我以前从未见过它。/expertsimages.liveperson.com/images/phonewidget/txt\u notavailable.png/symbol用于一次，\n用于两次。
