I was at Ubon Ratchathani Immigration almost 12 years ago and they had both photo and copy service available...I would assume they still offer those services today.
An SETV will get you 90 days in total..you are stamped in for 60 and then you extend at Immigration for another 30 days at the cost of Bt. 1,900....then you can apply at another embassy outside the country for another visa and repeat the process.
You are advised to switch embassies every now and then so you do not get too many back-to-back visas from the same place. otherwise you will bet refused (Red Stamp) and cannot use that embassy again.
