Pratiksha, NTA mentions that it is important to have Date and Name written on the passport size photo along with following the set instructions:

Uploading of Photograph: Instructions

The focus has to be on the face with 80% coverage and ears clearly visible.

Having said that, if you have already submitted the application form without writing the name and date on the photograph and if NTA finds that unacceptable, you can upload a new photograph during the correction window with date and name written on it. But if you do not receive any such notificiation from NTA, then you are good.
