loading picturebox image from file

Question

I tried these two approaches. Neither worked - the picture box remains empty. How can I fix the code? I must be missing something obvious.

 

1.

if (File.Exists(saveImageFileName))
{
   MessageBox.Show("Image file exists");
   tempImage = Image.FromFile(saveImageFileName);
   pictureBox.Image = tempImage;
}

2

if (File.Exists(saveImageFileName))
{
   MessageBox.Show("Image file exists");
   pictureBox.Image = new Bitmap(saveImageFileName); ;
}
