Rounded Corners on Images?

Does anyone know of any CSS or Javascript that I can use to give all my pictures rounded corners?

Code:

---

<div style="border: 2px solid black;
            border-radius: 30px;
            -moz-border-radius: 30px;
            -khtml-border-radius: 30px;
            -webkit-border-radius: 30px;
            width: 180px;
            height: 240px;
            background: url('http://www.animeviews.com/images/runaways.jpg');" />

This works in The latest versions of Opera, Firefox, and Chrome. I did not get this to work in IE8 and I do not have IE9. If anyone does have IE9 I would love to hear if this works in that browser.

I found the solution here. There were other javascript solutions and css javascript options, but I prefer straight css when I can get it.
