浏览器如果出现"stack overflow at line:0"并且有些图片无法显示的问题，是由于注册表被串改了

这是由于pngfilt.dll问题，解决方法如下

把以下内容保存到记事本，随便起个名字，并且把后缀改名为.reg，双击打开这个reg文件点“是”，添加入注册表中

再重启浏览器，看看是不是已经能显示了

下面再提供一个方法

在IE的选项的高级项里禁用脚本调试，试试 

开始...运行，入REGSVR32 URLMON.DLL，回车后重启系统，然后进入IE的“工具”→“Internet选项”→“程序”

单击“重置Web设置”按钮即可 

还有一个方法

1.运行-输入cmd-输入regsvr32 c:\windws\system32\pngfil.dll-囬车

 2.我的电脑-属性-高级-性能-设置-高级-更改-调整虛拟内存为4-确定
