Something like its

SQL: insert into Images(Image) values(:image)

Code:
procedure TForm1.Button1Click(Sender: TObject);
var Stream: TStream;
begin
  Stream := TMemoryStream.Create;
  try
    Image1.Picture.Bitmap.SaveToStream(Stream);
    Stream.Position := 0;
    Query1.ParamByName('Image').LoadFromStream(Stream, ftBlob);
  finally
    Stream.Free;
  end;
  Query1.ExecSQL;
end;

Finally I did it.... Thanx for your help. I was going mad, because i've been struggling with stream, memorystream,loadfromstream,...etc. for two days.
I was giving parameter as query1.params[0].AsBlob:= stream
That was my problem. i couldn't think of giving parameter in that way, ( two days...:))
when i gave parameter as above, it gave errors of incompatible types string and tstream. I typecasted it as string(stream)....whatever... Thanx for help.... Valla, if i had 200 points, i would give all for this answer (as i said 2 days...)...
