Hi all. When I am trying to create image like

  Image<Gray, Byte> testImage = new Image<Gray, Byte>("david.jpg");

When compiling it gaves An unhandled exception of type 'System.ArgumentException' occurred in System.Drawing.dllexception. But if I use

  DialogResult result = openFileDialog1.ShowDialog();
        if (result == DialogResult.OK || result == DialogResult.Yes)
        {
            textBox1.Text = openFileDialog1.FileName;
        }

        Image<Gray, Byte> testImage = new Image<Gray, Byte>( textBox1.Text);

It works.Problem is that it cant find path? I am adding all .jpg files in project folder.
