If there is a discrepancy in the uploaded images, NBE will notify the Candidates at their registered email and mobile number. Such Candidates have to login and make changes to the uploaded images during the correction window. Only those Candidates who receive such notification can make changes to the application form. Rest, needn't. So if you do not receive any communication from the authorities, consider your application to be good enough.
