Indexhibit Support

I've followed the path contained in this thread indexhibit.org/forum/thread/14016/

Here in the website ad it looks now.

I've changed the img-container to a hrz-container in the horizontal plugin.

Then i go to the style.css and i can't find neither the img-container or the hrz-container.
As the thread that i've linked before i've got the horizontal scroll changed into a vertical one.

Would you explain me where id the problem?

Thanks

Well you need to knoe code basics - css basics to be exact.
And centering the horizontal plugin will need a bit more than this.
