Any child must be protected by not revealing their identity. Section 4 of the Child Protection Act
defines “Child” means a person whose age is less than 18 years but does not include those who attain majority through marriage."
Section 50 of the Act says, " No person shall advertise or disseminate by means of mass media or any other form of information technology the disclosed information in violation of the provisions under paragraph one or paragraph two."
We should not photograph children and put those photos in the media without disguising their identity or getting written permission from their parents.
There are also defamation laws. One has to assume that using a photo with an article about prostitutes implies the photo is associating her with the story.
Your holiday photos may not be a problem, but if you are making money from photos I would be careful.
P.S. The Thailand personal data protection act (PDPA) does not specifically use the word photo but does say “Personal Data” means any information relating to a Person, which enables the identification of such Person, whether directly or indirectly, but not including the information of the deceased Persons in particular.
I take a photo to mean something that enables identification.
