winsock binary file transfer

Can anybody give me the necessary code to send a graphic file (Binary) and receive the same into a local intranet ??? Help please thanks

Send binary file

Private Sub cmdSend_Click()
On Error Resume Next 'prevents error
If txtFile.Text = "" Then Exit Sub 'wont let someone send something not there
strFileName = "" 'resets the filename
blnSend = False 'sets it to false
strSize = "" 'resets the size

Open txtFile.Text For Binary As #1 'opens the file u want to send so it can be read
strLOF = LOF(1) 'saves length of file into memory
Winsock.SendData "Name" & CD.FileTitle & ":" & strLOF 'sends server the name of the file and its length
DoEvents 'needed =D

Do While blnSend = False 'keeps looping until the server accepts the request
DoEvents 'lets u do stuff while in loop
Loop 'goes back to Do WHile statement

End Sub

Receive

Private Sub Winsock_DataArrival(ByVal bytesTotal As Long)

Case "File" 'a file transfer is in progress
Put 1, , strData2 'puts data into file
PBar.Value = PBar.Value + bytesTotal 'shows how much is done so far
strSoFar = strSoFar + bytesTotal 'calculates KBps
Winsock.SendData "OKOK keep sending!" 'tells them ur done with the data and u want some more!
DoEvents ' =D

'resets the progressbar
PBar.Value = 0
PBar.Max = 1
'=====================
Me.Enabled = True 'reenables the form!
Case "Nope" 'tells u that they declined ur request to give em a file
MsgBox strFriend & " declined your file transfer request.", vbInformation, "File Transfer Canceled!" '<=- easy to get again
