No, just screenshot of student id can do it.
But it must not be blurry to the extend that you cannot read the content of the id because the GitHub edu team would want to see if your name in the id matches with what I stated below 
Provided your GitHub billing information name,the profile name is exactly as your name on the student id and your account is two factor authenticated and you have not used VPN during application phase. You will be approved within minutes brother.
