Ideally it takes 24-72 hours for AIIMS to respond to your mails. Provisionally accepted registrations still have a chance to be edited provided AIIMS considers there are some changes required for the application form. And any discrepancy in the uploaded images need to be intimated by AIIMS for request in change. Or else, consider the uploaded image to be fine. But wait for the basic registration to be completely accepted by AIIMS.

Hello,

If they have not sent a mail specifying a mistake it is okay. NBE checks the thumbprint and photo and if there is any mistake they will inform you. As they have not informed then it must be fine. Also, the date for making changes is over and you cannot change your uploaded thumbprint.

So do not worry and focus on your studies.

All the best.

Hope this helps
