1- Is the picture for family members only (parents siblings). If so then you and any other women of your family probably can safely be in it. (And it will probably make your parent very happy to have a picture of their daughter)
2- If the picture is to be shown on public places like facebook, I would make sure to wear hijab properly as if you were outside walking on the street.
As far as I know (and my knowledge is very limited, so anyone, fell free to correct me), being in a picture in itself is not haram for a women. The problem is more where that picture ends up and more importantly who sees it.
