[local]1[/local]首先，现象是，你打开淘宝网无法显示其logo，打开某些需要输入验证码才能登陆的网站，不管你网速如何，都没办法打开其验证码图片。用鼠标右键一点，发现图片png格式的。其次，解决方法：
1.复制一下内容保存为XXX.bat，当然XXX你可以随便输哈。但是后缀就不要变了。
regsvr32 msxml3.dll
regsvr32 actxprxy.dll
regsvr32 shdocvw.dll
a.reg
2。复制一下内容保存为 a.reg 当然这个a是可以变的，如果变了，那么第一步中的a.reg也要修改为你改变的，然后再保存下。

3.最简单的就是这一步了。直接运行XXX.bat就是了，遇到提示直接敲回车就可以了
或者直接下载附件，然后运行 【 处理PNG不能显示问题.bat 】这个程序就可以了。
