Combobox binding 2000 pictures

[Mazz]

I'm really stuck here. I need a combobox to display 2000 pictures and when I click on any picture, it should display in a picture box. Here's my code but its not working..

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Picbox.BackgroundImageLayout = ImageLayout.Zoom

For index As Integer = 1 To 2000
cmb.Items.Add(index)
Next


End Sub


Please help me out ASAP. Thanks!
