Save MS Access BMP to SQL Server 2000

Hello,

I'm trying to store an MS Access Bitmap image to an SQL Server 2000 table via ADP. The field in SQL Server 2000 is image.

The code I'm using is:
Private Sub Command4_Click()

Dim rs As ADODB.Recordset
Set rs = New ADODB.Recordset
Dim formQuery As String

formQuery = "SELECT * FROM tblImageData"

rs.Open formQuery, CurrentProject.Connection, , adLockOptimistic

With rs
.AddNew
.Fields("ImageDescription") = Me.Text5
.Fields("ImageData").AppendChunk Me.Image3.PictureData
.Update
.Close
End With

End Sub

This results in a Run-time error '-2147217887(80040e21)'

Thanks for the help and sorry for originally posting this in the Access forum.
