Users can set his profile picture from admin end and as well as Front End.
Admin End it would come automatically based on the user role, who has upload_files capability, otherwise we need to assign capability to them.
In Front End when we use <?php do_action('edit_user_profile',$current_user); ?> on edit profile section, it would be placed on additonal user profile fields.
*Future Updates: Display current user images alone, short code and migrate withsocial media profile pictures.
