Here it is:

procedure TForm1.Button2Click(Sender: TObject);
var
  WndDC: HDc;
  WndRect: TRect;
  WndCanvas: TCanvas;
  Wnd: HWND;
  WWidth, WHeight: Integer;
begin
  Image1.AutoSize := false; // important!!!
  Wnd := GetDesktopWindow;
  WndDC := GetWindowDC(Wnd);
  WndCanvas := TCanvas.Create;
  WndCanvas.Handle := WndDC;
  GetWindowRect(Wnd, WndRect);

  WWidth := WndRect.Right - WndRect.Left;
  WHeight := WndRect.Bottom - WndRect.Top;

  Image1.Width := WWidth;
  Image1.Height := WHeight;
  Image1.Canvas.CopyRect(Rect(0, 0, WWidth, WHeight), WndCanvas, Rect(0, 0, WWidth, WHeight));
  WndCanvas.Free;
  ReleaseDC(Wnd,WndDC);
end;

Transfer the bitmap as Stream using the
Server/Client socket components.

It works pretty well.

Posting the code in here would be a bit too much, but you can have a look at the example shipped with delphi.

It shows you the basics of using the socket-components.

It's in $(DELPHI)\DEMOS\INTERNET\CHAT


feel free asking me further questions
