一个网页，它是显示图片，但在一些浏览器，它却显示如下：
Insus.NET猜，不是浏览器不兼容，就是代码有问题。
在代码中，只是输出数据流，图片格式很多种，如jpg,png,bmp等，没有指定，程序也不清楚要显示什么格式的图片。
因此，Insus.NET把代码改为如下：
context.Response.Buffer = false; FileStream inStr = null; byte[] buffer = new byte[1024]; long byteCount; inStr = File.OpenRead(path); while ((byteCount = inStr.Read(buffer, 0, buffer.Length)) > 0) { if (context.Response.IsClientConnected) { context.Response.ContentType = "image/png"; context.Response.OutputStream.Write(buffer, 0, buffer.Length); context.Response.Flush(); } } 另外，附上ContentType，日后可以参考与查阅：
