picture box issue

[operator]

Hello all,
I have a very minor problem with my code. I can display the image in the picture box however I cant clear it.Here is my code;

if (cmbCountry.SelectedItem == "Türkiye")
{
Bitmap bmp = new Bitmap("C:/Documents and Settings/erdemem/My Documents/My Pictures/tr.gif");
pictureBox1.Image = bmp;

Question: I have a "clear" button in my form. How can I clear the image above when the clear button is hit?
Regards,
Erdem

pictureBox1.Image = NULL;

[operator]
