How about something like this:

Private Sub PicBoxTestButton_Click(sender As System.Object, e As System.EventArgs) Handles PicBoxTestButton.Click
    Try
        Dim numberOfPics As Integer = ListBox1.Items.Count
        Dim lastLeft As Integer = 15
        Const spacer As Integer = 5
        For parser As Integer = 0 To numberOfPics
            Dim PicBox As New PictureBox
            PicBox.Width = 40
            PicBox.Top = 25
            PicBox.Left = lastLeft
            lastLeft = PicBox.Width + PicBox.Left + spacer
            PicBox.SizeMode = PictureBoxSizeMode.StretchImage
            PicBox.BorderStyle = BorderStyle.FixedSingle
            Me.Panel2.Controls.Add(PicBox)
        Next
    Catch ex As Exception
        MessageBox.Show(String.Concat("An error occurred: ", ex.Message))
    End Try
End Sub
