Centering Easing Slider for NOOB

Hi everyone,

First I apologize for opening another topic, but the existing one did not help.

OK so, Easing slider V1.2 is all installed and working. I Need to center it in the page. here s the domain : http://www.siteandsight.com
I am a real supernoob at this and I seriously do not understand how this whole centering thing works.

Can anyone please help me step by step ?

Thanks,
Julien
