To use this the following code:

OpenFileDialog1.Filter = "Bmp Files(*.bmp)|*.bmp|Gif Files(*.gif)|*.gif|Jpg Files(*.jpg)|*.jpg"
 OpenFileDialog1.ShowDialog()
 Textbox1.Text = OpenFileDialog1.FileName
 PicText.Image = Image.FromFile(OpenFileDialog1.FileName)

I would say that the easiest way is to paint the background when the image object is created (sample initializing the background to being white):

Dim theImage As Image = New Bitmap(someWidth, someHeight)
Using g As Graphics = Graphics.FromImage(theImage)
    g.Clear(Color.White)
End Using
