Add first row - ok.
Add second: watch image in second from the start and first from the end.

The tableview and listview cells are reused to render different row data of the source list. Your problem probably lays on the updating of the cell item. Try this:

@Override
public void updateItem(CarPhoto item, boolean empty) {
    super.updateItem(item, empty);
    if (!empty && !item.equals(null)) {
        imageview.setImage(new Image(item.getPhoto()));
    }
    else {
        imageview.setImage(null);
    }
    System.out.println(item);
}
