can i change my photo uploaded on my application form.plzguide me

Pradeep, you have not mentioned which exam you are talking about. Since the NEET correction window is open currently, I would be answering for it. If the question was meant for some other exam, please mention in the comments section.

So for NEET 2020, the answer would be no. You cannot change your photo or any other uploaded documents during the correction period unless you have been notified by NTA to do so via SMS and email, due to some error in the images.

The correction window is open from 15 January to 31 January 2020 and you will get an intimation from NTA if the photo needs to be changed. If there is no such message, you cannot edit the uploaded image on your own. Also you can be assured that your upload is correct according to the guidelines and does not require to be changed.
