your code is not correct because Start function need filename as a parameter which is not what you are passing so its taking as a invalid parameter.
you can use
WindowsFormsApplication2.Properties.Resources.photo
to assign value to pictureBox1.Image to display images in image control.
as
pictureBox1.Image = WindowsApplication2.Properties.Resources.photo;
