UPLOAD JPG through http

Hi
I am using follwing code to upload jpg file
void CreadbmpDlg::OnBnClickedPressl()

DWORD dwChunkLength;
DWORD dwReadLength;
DWORD dwResponseLength;

//Create the multi-part form data that goes before and after the
actual file upload.
CFile file(_T("upload.txt"),CFile::modeRead);
CString strHTTPBoundary = _T
("FFF3F395A90B452BB8BEDC878DDBD152");
CString strPreFileData = MakePreFileData(strHTTPBoundary,
file.GetFileName());
CString strPostFileData = MakePostFileData(strHTTPBoundary);
CString strRequestHeaders = MakeRequestHeaders(strHTTPBoundary);
dwTotalRequestLength = strPreFileData.GetLength() +
strPostFileData.GetLength() + file.GetLength();

connection = session.GetHttpConnection
("www.mydomain.com",NULL,INTERNET_DEFAULT_HTTP_PORT);

t.php"));
pHTTP->AddRequestHeaders(strRequestHeaders);

//Write out the headers and the form variables
pHTTP->Write((LPSTR)(LPCSTR)strPreFileData, strPreFileData.GetLength
());

//upload the file.

dwReadLength = -1;
int length = file.GetLength(); //used to calculate percentage
complete.
while (0 != dwReadLength)
{
    dwReadLength = file.Read(pBuffer, dwChunkLength);
    if (0 != dwReadLength)
    {
    pHTTP->Write(pBuffer, dwReadLength);
    }

}

file.Close();

//Finish the upload.
pHTTP->Write((LPSTR)(LPCSTR)strPostFileData, strPostFileData.GetLength
());
pHTTP->EndRequest(HSR_SYNC);

//get the response from the server.
LPSTR szResponse;
CString strResponse;
