我记得之前好像是可以访问本地的路径的，我刚试了不行了，可能我记错了
你这样要访问 你就配置一个E：/images 为跟目录的 域名
echo '<img src="' . $GW_UPLOADPATH . $screenshot . '" alt="Score image" /></p>';
这里把 $GW_UPLOADPATH 改成你配置的域名就可以

对的 我已经找到问题了 因为我把images建在了错误的地方 才一直move file wrong ，D:\xampp\htdocs\myphp\myphp\myphp\guitar\images建在这里就成功显示图片了 （我要找个方法简化下。。。。）（不过当前项目要是没有images文件夹 就会出错，我还以为它会自己新建一个images文件夹呢）
谢谢你的回复 我已经找到方法了 修改域名的方法我会尝试一下的 路径这么长我看着也头晕

浏览时，图片路径是从网站根目录算起的
你的 E:/images/ 是文件系统目录，不是网站目录
你的 E:/images/ 是文件系统目录，不是网站目录

下面是addscore.php
红圈这里路径这样填对么
这样填的话 图片不知道为什么会存在E:\ 里 而不是E:\images 里 而且 图片的名字前面会加上images
我现在遇到的问题是 图片可以上传到本地服务器，但是不能显示图片，求大佬解答！！
