Zayn, if you havent received any notification from NTA, it means that all your uploaded images are within NTA's guidelines. However, the 'edit' option has been made available for Candidates who want to upload images on their own jurisdiction. So now if you feel that the images need to be changed, click on Edit button and make the changes. But if you want to wait from NTA, you may do so. But whichever way you choose to upload the images, make sure to take the print out of the confirmation for all future references.
