Problem with savefiledialog

[Splatch]

Hi,

When I save my picturebox no matter what the background colour is, it gets set to black. Does anyone know why it is doing this?

Here is the saving code:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim saveFileDialog1 As New SaveFileDialog()
saveFileDialog1.Filter = "JPeg Image|*.jpg"
saveFileDialog1.Title = "Save an Image File"
saveFileDialog1.ShowDialog()


If saveFileDialog1.FileName <> "" Then

Dim fs As System.IO.FileStream = CType _
(saveFileDialog1.OpenFile(), System.IO.FileStream)

Select Case saveFileDialog1.FilterIndex
Case 1
Me.PictureBox1.Image.Save(fs, _
System.Drawing.Imaging.ImageFormat.Jpeg)


End Select

fs.Close()
End If
End Sub


The rest of this of the code is basically just comboboxes and a little reset code.


Thanks in Advance
