IE8 无法显示 .PNG 图像

IE8 无法显示 .PNG 图像

我真的不知道用户是如何做到这一点的，但由于某种原因，.PNG 图像在 IE8 中不再起作用。

当查看包含 .PNG 图像的页面时，它们只会显示一个小红色 X。直接导航到图像也只会显示一个小红色 X。

我努力了：

  • 重新安装 IE8。
  • 重置 IE8 设置。
  • 以不同的用户身份登录以查看 .PNG 是否显示正常，结果是可以的。
  • 正在运行病毒扫描。
  • 运行 Malwarebytes。
  • 运行 Spybot 搜索并销毁。
  • 使用 HijackThis 删除一般垃圾。

我可以重新格式化机器，但我宁愿解决这个问题也不愿这样做。

操作系统是Windows XP SP3

您的 MIME 类型可能设置不正确（可能是由于过去的间谍软件或失败的附加组件）。

答案2

经过几天的工作，我在用户特定的注册表中发现了问题：

当我删除此完整条目时，.png 图片在 IE8 以及 Eudora 或 StarMoney 等其他应用程序中显示正常

此条目由病毒 TR/SPY.LURK.21 创建

据悉这里

我发现问题所在，因为我的系统上有另一个用户，可以正确显示 .png。因此，我导出了此用户（非常小）和受感染用户的注册表。在进行以下测试之前，我自然而然地在系统中写入了一个重启点（我需要！）。然后，我删除了受感染用户的注册表并导入了正确的注册表。由于它有效，我只删除了部分内容并导入，直到我发现问题。
