Slideshow control for use in WordPress Thesis theme – non flash

I want to use a good elegant slideshow control in my website. The website is created in wordpress and I am using the Thesis theme.

I did find a Nivo slider but am stuck at the integration with Thesis (using the custom functions and custom css files).

Can someone suggest a good non-flash slideshow widget which I can easily integrate with the theme (and also how to integrate it)

Thanks.

Here is a list with some of the widgets: http://www.geeksucks.com/showcases/12-awesome-wordpress-slideshow-plugins.htm
