Dear Harshal, you can only make corrections to your uploaded photograph if you have been notified by NTA to do so. NTA will send a notification to your registered Email and Mobile number asking you to make changes to your photograph or signature. Only those Candidates can and need to make corrections to the uploaded photograph and signatures. Please check if you have received any such notification. If you did not, then you are good and you do not need to make any changes to your application.
