Hello aspirant,

NO, you do not necessarily need to paste the same photograph of yourself in the Examinations as was uploaded in the JEE mains ADMIT Card. But if you still have the same photograph, you can paste the same, but if you do not have the same photograph, you can even paste the new fresh photograph of yourself with your face clearly seen.
