Application.Wait does skip some commands

If I use the command "Application.Wait (1)" the programm skips the next command. I am using Application.Wait inside a for-loop.

I am using this code:

    For i = 1 To 34
        Application.Wait (2)
        Call Rechts
    Next i

This Code copy on each round a picture in a picture-box. But actually the code copy only the last one in the picture box. On the End it should looks like a slideshow.

How can I wait one second in a For-Loop?
