sorry ,i uploaded wrnog photo and application submited ,can i change it again 

Dear aspirant,

If there is an option to reupload the photo or if you have not finalised the form then you can rechoose a file to be uploaded. Incase none of this applies to you and you have either fianlised the photo or haven't been provided with the reupload button then when ever you visit the document verifiation centre, be sure to carry the soft as well as a hard copy of you photo in the required size to the centre and make sure you approach the head or incharge at the centre, they can usually reupload or re do the documents and the photo.

Thankyou

Dear questioner, 

Please clear what you want to know about. Your query is incomplete. If you are asking about how to upload correct photo then you can choose the required file, if further problem comes you should contact one, to whom you are doing the same.
