Slideshow missing animation

Slideshow missing animation

I found this beautiful website (http://soworldwide.org/) and wanted to
create a similar slideshow.
After I've spend a lot of time to make it work, I still have problems with
it. It's shows the first 3 slides as I want (a bit too slow), but when all
the slides has been showed and the slideshow has to show the first picture
again, then I wont make the vertical animation. It's seems like it needs
to refresh everytime the cycle is over before it can make the animation
again.
The problem must be in this area somewhere. I just can't figure it out,
and I desperately hope a clever person out there can help me. I'm using
the same jquery cycle pluin by the way.
$(document).ready(function(){
$('#myslides').cycle({
fx: 'custom',
cssBefore: { top: 0 },
animIn: { top: 0 },
animOut: { top: -500 }
Thank you in advance.
