Change the header animation

I'm trying to change the animation that appears in the header of the Startup template (The laptop, ipads and mobilephones in front of the background image) but i can't figure out where i can control the animation. Can you help me?

Hi,
it is Image Show module. Please go to the module settings.

Thanx, but it's not the content i want to change. What I want to do is for example to change so the images flies in from left to right instead of from top to bottom like it is now.

Unfortunetly it is extra customization and we don't support it.
