Dim Offset As Point
Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs) Handles PictureBox1.MouseDown
     Offset = New Point(-e.X, -e.Y)
End Sub

Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As MouseEventArgs) Handles PictureBox1.MouseMove
     If e.Button = Windows.Forms.MouseButtons.Left Then
         Dim Pos As Point = Me.PointToClient(MousePosition)
         Pos.Offset(Offset.X, Offset.Y)
         PictureBox1.Location = Pos
     End If
    End Sub
