I can’t help with your photo problem.. but I would advise you not to go to the thai embassy at 08:00 and join the huge queue and stand for 2 hours .. I went a couple of weeks ago ( also on a Monday ) at 11:00 .. on a handful of people queuing I was number 517
And when collecting passport the next day . I didn’t go at 1:30like everyone else and queue and wait and not. A sit .. I went at 3:15 .. and my number had been called a few minutes before , so I joined a short queue - easier
And if you go to Embassy at 11:00. - you have time to find Kodak shop open Monday morning
