Passing Image to PrintPreviewDialog

[fret]

Hi guys,
I have a problem here, I have an image from certain file path. Now what I want to do is to pass that image to the printpreviewdialog in order to show that image and I don't know where to continue with this sample code:

private void button1_Click(object sender, System.EventArgs e)
        {           
            PrintPreviewDialog t = new PrintPreviewDialog();
            printDocument1.PrintPage += new PrintPageEventHandler(pr);
            t.Document = printDocument1;
            
            t.ShowDialog();
            
        }
 
        private void pr(object sender, PrintPageEventArgs e)
        {
            // where source image came from
            Image i = Image.FromFile("C:\\idBack.jpg");
            i.Dispose();
        }

It appears to be blank paper, I know there's missing here.
