WebPlus X6: Feathered images slider... is it possible

I would like to display 3 or 4 fading images, perhaps by adapting one of the WPX6 sliders. But I would want to use feathered images (e.g vignetted with blurred edges) without any frames displaying, so it looks like an integral part of my page. If not with sliders...any other ways this could be done?

Thanks
Mike
