Hey Vinu!

Although your uploaded photographs don't contain the birth date and name, it would not create any serious problem. Even uploaded photographs without name and birth date should be good enough and sufficient for NTA. However, if there is any problem about the photographs, you would get a mail or notification from NTA. You can change the photographs if you get mail from NTA only but if you don't get any notification from NTA regarding the photographs, then your uploaded ones are good enough and you don't need to worry. So, wait for NTA notifications for uploaded photos and if you don't get it then your photos were perfect.

Hii Vinu!
Sorry, but you can't change your photograph and certain details until NTA has specified it to you through sending an email or a message. So, what you can do now is to wait for the notification to come. If you are still doubtful, you can visit the NEET UG official website and contact the helpdesk. They may help you with this. Hope you understand.
Good luck!
