hi.. i found this steganography code and i run it..but i dont know what type of method it is..i want to know what types of method is this. it is LSB method? anyone can help?

Dim PlainText As String = TextBox2.Text
                Dim PlainTextByteArray(PlainText.Length) As Byte
                For i As Integer = 0 To (PlainText.Length - 1)
                    PlainTextByteArray(i) = CByte(AscW(PlainText.Chars(i)))
                    Application.DoEvents()
                Next
                Dim PicAndText(PicBytes + PlainText.Length + SentinelString.Length) As Byte
                For t As Long = 0 To (PicBytes - 1)
                    PicAndText(t) = PicByteArray(t)
                Next
                Dim count As Integer = 0
                For r As Long = PicBytes To (PicBytes + (SentinelString.Length) - 1)
                    PicAndText(r) = SentinelString(count)
                    count += 1
                Next
                count = 0
                For q As Long = (PicBytes + SentinelString.Length) To (PicBytes + SentinelString.Length + PlainText.Length - 1)
                    PicAndText(q) = PlainTextByteArray(count)
                    count += 1
                Next
                SaveImage.ShowDialog()
                Dim NewFileName As String = SaveImage.FileName
                My.Computer.FileSystem.WriteAllBytes(NewFileName, PicAndText, True)
