I heard ther's a booth at Ekkamai bus station? Not sure whereabouts is it though.

They're pretty rare around here. I spotted one over at Gateway Ekkamai, but every time I swing by, it’s always out of order.

Yeah, I'd say if you can't find one at a mall, you're probably gonna have to call into one of those little shops with a guy and a camera. It seems to be the main way to get passport photos in Thailand. I usually use the shop in Siam. I think it's a street or two back from the main (BTS Siam) road.

Thanks everyone! 😉 👍
