How do I save an image to SQL that I have pasted into a picturebox via the clipboard?

I have a picturebox on my WinForm.  The user inputs an image and it is saved into SQL.  

If the saved image is a file and the user does this, the picture is saved and retrieved from SQL perfectly.  

To input the image:
Dim openFileDialog As New OpenFileDialog

If openFileDialog.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
            PictureBox1.Image = System.Drawing.Image.FromFile(openFileDialog.FileName)
End If

To save the image:
If PictureBox1.BackgroundImage IsNot Nothing Then
                Dim ms As New MemoryStream()
                PictureBox1.BackgroundImage.Save(ms, PictureBox1.BackgroundImage.RawFormat)
                Dim data As Byte() = ms.GetBuffer()
                tblH.errImage = data
End If

To retrieve the image:
If tblH.errImage IsNot Nothing Then
Dim picImage = (tblH.errImage).ToArray()

If picImage.Length > 0 Then
                Dim stream As MemoryStream
                Dim img As System.Drawing.Image
                stream = New MemoryStream(picImage)
                img = System.Drawing.Image.FromStream(stream)
                PictureBox1.Image = img

            End If
Else
            Me.PictureBox1.Image = Nothing
            Me.PictureBox1.Refresh()
End If

But when I use the clipboard to insert the image, the system throws an error when I try to save it.  

This Is the error:
An unhandled exception of type 'System.ArgumentNullException' occurred in System.Drawing.dll
Additional information: Value cannot be null.

I am using this code to insert an image from the clipboard:

If My.Computer.Clipboard.ContainsImage Then
            PictureBox1.BackgroundImage = My.Computer.Clipboard.GetImage
            PictureBox1.BackgroundImageLayout = ImageLayout.Zoom
Else
            MsgBox("Your clipboard does not contain an image.")
End If

If I change backgroundimage to image, it does the same thing.   I also see there is a value in PictureBox1.BackgroundImage.RawFormat so I don't understand the null value error.

I'm not sure where to check next so any direction will be greatly appreciated!
Many thanks!!

This line is your problem:
PictureBox1.BackgroundImage.Save(ms, PictureBox1.BackgroundImage.RawFormat)

Try This:
PictureBox1.BackgroundImage.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg) ' or whatever format you want.
