C语言实现的web服务器，浏览器上无法显示图片
这是我的代码，实现的是服务器，可以显示文本，但是无法显示图片。。。。
这里是代码：
#include <WinSock2.h>
#include <iostream>
using namespace std;
#define BUFFER_SIZE 1024
#define HOST "127.0.0.1"
#define PORT 8000
#define HEADER "\
HTTP/1.1 200 OK\r\n\
Content-Type: text/html; charset=UTF-8\r\n\
Server: ZYhttp_v1.0.1\r\n\
Content-Length: %ld\r\n\r\n\
"
const string strPath = "index.html";
#pragma comment(lib, "WS2_32")
// 获取文件的大小
long GetFileLength(string strPath);
// 单线程函数
int main(int argc, char** argv)
{
// 定义并且初始化一个服务器套接字
sockaddr_in addrServer;
addrServer.sin_family = AF_INET;
addrServer.sin_addr.S_un.S_addr = INADDR_ANY;
addrServer.sin_port = htons(PORT);
// 初始化
WSADATA wsaData;
WORD socketVersion = MAKEWORD(2, 2);
if (WSAStartup(socketVersion, &wsaData) != 0)
{
printf("初始化失败!");
exit(1);
}
// 创建套接字
SOCKET socketServer = socket(AF_INET, SOCK_STREAM, 0);
if (socketServer == SOCKET_ERROR)
{

exit(1);
}
// 绑定服务器套接字

// 监听

}
while (true)

//服务器端建立连接

break;
}
char buffer[BUFFER_SIZE];
memset(buffer, 0, BUFFER_SIZE);
//接收数据

}
printf("接收到的数据 : \n%s", buffer);
// response
// send header
memset(buffer, 0, BUFFER_SIZE);
sprintf(buffer, HEADER, GetFileLength(strPath));//把文件和头文件合并然后发送数据
if (send(socketClient, buffer, strlen(buffer), 0) < 0)
{

break;
}
//读取文本
ifstream fin(strPath.c_str(), ios::in | ios::binary);
if (fin.is_open())
{
memset(buffer, 0, BUFFER_SIZE);
//每次读取一个字节
while (fin.read(buffer, BUFFER_SIZE - 1))
{

{

break;
}
memset(buffer, 0, BUFFER_SIZE);
}
if (send(socketClient, buffer, strlen(buffer), 0) < 0)
{
printf("发送数据失败!");
break;
}
}
fin.close();
closesocket(socketClient);
}
closesocket(socketServer);
WSACleanup();
return 0;
}
long GetFileLength(string strPath)
{
ifstream fin(strPath.c_str(), ios::in | ios::binary);
fin.seekg(0, ios_base::end);
streampos pos = fin.tellg();//返回当前文件位置
long lSize = static_cast<long>(pos);
fin.close();
cout << "该文件的长度：" << lSize << endl;
return lSize;

我不知道是什么问题，这些代码也比较短，请大佬们指个路，实在不会了。。。。。感谢感谢，磕头了。。。。
真的不会啊，有大佬就麻烦指个路啊，救人一命胜造七级浮屠。。。。。。。。。
