ThinkPHP验证码显示问题,求大神解释!!!
这是代码:

<p>验证码:<input type="text" name="vircode" onkeyup="return login_chkcode( this );" style="width:100px;" maxlength="4" /><img src="/static/imghwm/default1.png"  data-src="__URL__/verify/"  class="lazy"  id="login_verifyImg"  onclick="return login_fleshVerify();"   style="max-width:90%" alt="点击刷新验证码" title="点击刷新验证码" /><label id="login_vircode"></label></p>

然后在本地显示正常:

然后传到服务器上之后:

然后ff报错如下:

这个是验证码代码:
function verify() {<br />
        import("ORG.Util.Image");<br />
        Image::buildImageVerify();<br />
    }


请大家帮忙看看,这怎么上传到服务器上之后就不显示了呢??
------解决方案--------------------
function fleshVerify() {
//重载验证码
var timenow = new Date().getTime();
$('#verifyImg').attr("src", "{:U('Admin-Login/verify/')}" + timenow);
}//这是js

//你是不是没有上传完整啊
------解决方案--------------------
服务器上是否已开 GD库的扩展?
