This function converts byte array to image:

Public Shared Function ByteArrayToImage(ByVal ByteArr() As Byte) As Object
                Dim ImageStream As System.IO.MemoryStream
 
                Try
                    If ByteArr.GetUpperBound(0) > 0 Then
                        ImageStream = New System.IO.MemoryStream(ByteArr)
                        Return Image.FromStream(ImageStream)
                    Else
                        Return Nothing
                    End If
                Catch ex As Exception
                    Return Nothing
                End Try
            End Function


and this convert back:

 Public Shared Function ImageToByteArray(ByVal NewImage As Image) As Object
                Dim ImageStream As System.IO.MemoryStream
                Dim ByteArr() As Byte
 
                Try
                    ReDim ByteArr(0)
                    If NewImage IsNot Nothing Then
                        ImageStream = New System.IO.MemoryStream
                        NewImage.Save(ImageStream, Imaging.ImageFormat.Jpeg)
                        ReDim ByteArr(CInt(ImageStream.Length - 1))
                        ImageStream.Position = 0
                        ImageStream.Read(ByteArr, 0, CInt(ImageStream.Length))
                    End If
                    Return ByteArr
                Catch ex As Exception
                    Return Nothing
                End Try
            End Function


+You need DBNull check when the column allow nulls.
