Hi

No, you can't change your photo in NEET 2017 application form/ Admit card/ Results.

This is because,

It's already been 5 years. One change photo only during correction window opening, and can never change later on.

Moreover,

Now, your neet 2017 isn't valid for getting admission.

This is because,

--------------------------) For  admission in India, marks obtained by you in neet is valid for only one year i.e it is valid only the year in which you attempt the exam

--------------------------)   While for admission in abroad,  Marks obtained by you in neet is valid for 3 years.
