Rounded Corners Problem

I followed this guide (http://www.albin.net/CSS/roundedCorners/) to making rounded corners. And it works perfectly in Firefox, but in Internet Explorer it leaves a little area around the images and its messed up.
(see attached image)
My site is http://www.noveis.net and you can see my CSS at http://noveis.net/styles/css/base.css.
I know the problem isn't any of my other CSS not from the guide because I tried taking it all out.
Thanks!

Try using this free web-based tool to make your round corners. It also makes the HTML for you.

IE5.0 WIN - IE5.5 WIn all works fine
Seems IE6 problem only could be because of the margins .. ?

These are also good tuts on rounded corners:

Other dont use alt="&nbsp;" as it does not provide any ALTernative text info on the images, also decorative images can do without the alt, just do <img src="someImage.gif "alt="" ...>"
