文件夹缩略图不显示幻灯片不显示

在“开始→运行”中输入“regsvr32 shimgvw.dll ”（启用图像预览）；然后运行“regsvr32 shmedia.dll” （启用影像预览），注册DLL后应该会弹出窗口提示“……中的……成功”，按确定即可。如果要取消预览，比如取消视频预览，运行“regsvr32 /u shmedia.dll”即可。

不行的话再尝试：

“开始→运行”: 键入 regsvr32 C:\Windows\System\thumbvw.dll

缩略图不显示怎么办？ (2009-04-04, 09:47) 解决这个问题的方法是使用后面提供的一个vbs脚本程序。这个vbs脚本程序专门修改与“缩略图”浏览方式相关的注册表项，从而恢复“缩略图”浏览功能。**

使用方法如下。**

1 打开记事本程序。**

2 把下面的vbs代码复制下来，粘贴到记事本里，一定是记事本，不是文本文档。**

3 在记事本里选择“另存为”，将文件命名为：repairimage.vbs，并保存到桌面或其他能快速找到的地方。**

4 鼠标双击 repairimage.vbs 脚本文件。**

5 OK**

本地搭建的时候
缩略图保存的路径和你上传服务器后的路径不一样了，路径错了，所以不显示。逐个修改一下缩略图的地址，就可以了。

以上代码复制到记事本，重命名为 fixthumbnails.vbs 后双击运行，我前不久也遇到这个问题，就是这样解决的。
********************************************************************
PS：与一楼代码略有不同，希望对你会有所帮助。

另，一楼所说“一定是记事本，不是文本文档”，还真不知道记事本和文本文档有啥区别，大概是想说写字板吧.....

文件夹里面有图片吗
