Kullanımı: 

procedure TForm1.Button1Click(Sender: TObject);
begin
  SaveWBFrames(Webbrowser1);
end;

Alternatif Yöntem:

//Uses' a ActiveX; ekleyelim.

function TForm1.GetFrame(FrameNo: Integer): IWebbrowser2;
var
  OleContainer: IOleContainer;
  enum: IEnumUnknown;
  unk: IUnknown;
  Fetched: PLongint;
begin
  while Webbrowser1.ReadyState <> READYSTATE_COMPLETE do
    Application.ProcessMessages;
  if Assigned(Webbrowser1.document) then
  begin
    Fetched := nil;
    OleContainer := Webbrowser1.Document as IOleContainer;
    OleContainer.EnumObjects(OLECONTF_EMBEDDINGS, Enum);
    Enum.Skip(FrameNo);
    Enum.Next(1, Unk, Fetched);
    Result := Unk as IWebbrowser2;
  end
  else
    Result := nil;
end;

Örnek sayfayı yükleyelim.

procedure TForm1.Button1Click(Sender: TObject);
begin
  Webbrowser1.Navigate('http://www.warebizprogramming.com/tutorials/html/framesEx1.htm');
end;

// Tüm kareleri tek dosyaya kaydedelim.

procedure TForm1.Button2Click(Sender: TObject);
var
  IpStream: IPersistStreamInit;
  AStream: TMemoryStream;
  iw: IWebbrowser2;
  i: Integer;
  sl: TStringList;
begin
  for i := 0 to Webbrowser1.OleObject.Document.frames.Length - 1 do
  begin
    iw := GetFrame(i);
    AStream := TMemoryStream.Create;
    try
      IpStream := iw.document as IPersistStreamInit;
      if Succeeded(IpStream.save(TStreamadapter.Create(AStream), True)) then
      begin
        AStream.Seek(0, 0);
        sl := TStringList.Create;
        sl.LoadFromStream(AStream);
        sl.SaveToFile('c:\frame' + IntToStr(i) + '.txt');
        //  memo1.Lines.LoadFromStream(AStream);
        sl.Free;
