Earlier quoted context omitted.
Most companies strongly discourage you from submitting headshots already. At this point, it's considered unprofessional to submit a picture on an application.
Headshots are expected in CVs in the vast majority of the world. To my knowledge the big exceptions are US, UK, Canada, and Australia. But even there it's more like an "exception" since there's generally an unstated expectation that an employer can find more information, including a headshot, of you online.
