Where good place to get them done at decent price need to update mine

The Kodak shop opposite the Hilton.

Last time I checked, the Kodak shop there has closed down. Instead, try the Kodak shop near the Collonade mall on the main road, there's one just a bit further along there somewhere, they do them upstairs with a proper screen etc

Pretty much any shop with the Kodak sign.

Do not go to the Kodak shop on Petchakasaem Rd. near Soi 63

2 days ago asked for passport photos size 2 x 2 which are required for US Passports. Paid and they handed me the smaller size. When explaining they are too small the girl said they are fine. I insisted the US Embassy requires the 2 x 2 size, she wanted to charge full price for another set., I then walked out, very unprofessional, that store is not recommended.

The photo shop on AMNUAYSIN Road (eastern section) left hand side as you look down to the Phetchakasem Road provides a 30 minute inexpensive service for Passport and Immigration photographs and they KNOW the required standard and sizes!
