For Loop on imageList (picturebox) - vb.net

Hi Experts,

I have a winform with a Button, picturebox and imagelist. The imagelist only has 3 images embedded.

I simply want to click button1 and it shows image0, then if clicked again, image1, then if clicked again.. image 2... then loop if clicked.

 Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Dim i As Integer
        For i = 0 To 2
            PictureBox1.Image = ImageList1.Images(i)
            i = i + 1
        Next
    End Sub

Select allOpen in new window

My code only shows image0...

Help!
