Hey aspirant!

Uploading the passport size and postcard photographs without name and date need not be corrected and so they won't create any problems to you hopefully. However, NTA will notify you in case of any problems or corrections and only then you can correct anything. You can't correct anything until NTA has notified you for any mistake. As long as NTA doesn't send you a notification for this matter, you have no reasons to worry and your uploaded image is good and without any problems.

Hope this helps.
