truyền ảnh từ C/C++ client lên php server dùng http request

các pro cho em hỏi, muốn truyền 1 ảnh jpeg từ 1 client lên php server, code của em chạy ở local host thì được nhưng khi chuyển code lên host ip tĩnh free thì không chạy. em nghĩ là file .php trên host của em chua nhận được request từ client?
Đây là code client:

#include <iostream>
#include <winsock2.h>
#include <string>
#include <fstream>
#include "windows.h"
#include "stdio.h"

using namespace std;

#define PORT       80
//#define IP       "themnx-001-site1.1tempurl.com"
#define IP         "vitrafficesrc.freevnn.com"
//#define IP         "127.0.0.1"
//#define RECEIVER   "/myproject/createFD.php" //receive_data.php"
//#define RECEIVER   "h:
oothome	hemnx-001wwwsite1createFD.php"
#define RECEIVER   "/createFD.php"
#define COMPNAME   "compname"
#define PROGRAM    "program"

Đây là code server:

        fwrite($dst, base64_decode(fread($src, $CHUNK_SIZE)));

    fclose($dst);

    echo 'OK!';

Có ai biết giải thích tại nguyên nhân, cách debug không ạ? có code thì càng tốt ạ.
hoặc có ai không dùng http mà chạy được cũng được ạ.

cảm ơn các pro nhiều!
