Бизнес объекты и картинки

Задача такая, передать в FastReport бизнес-объект с катринкой

    public class Human
    {
        public string Name;
        public Bitmap photo;
        public int num;

        public Human(string name, int number)
        {
            Name = name;
            num = number;
        }
    }

....
            List<Human> peoples = new List<Human>();
            Human h = new Human("Human",  1);
            h.photo = (Bitmap)global::WindowsApplication1.Properties.Resources.Test2;
            peoples.Add(h);

            Report report = new Report();
            report.RegisterData(peoples, "Peoples", FastReport.Data.BOConverterFlags.AllowFields, 5);

            report.Design();

В дизайнере кладем объект Рисунок на бэнд и пивязываем его к полю Peoples.photo.
Далее строим отчет, все нормально. Закрываем превью и снова строим отчет - появляется ошибка:
