Very simple, basic slideshow needed

I need to transition just 2 or 3 photos (see http://www.westaffvt.com/westaff/images/homeSplash.jpg) at http://www.westaffvt.com/westaff/.

Here’s the code within a Page called home: <img id =”bg” src=”images/homeSplash.jpg” />

I just “inherited” this WP site and just starting to find my way around but a quick solution to get 2 or 3 photos cycling would be greatly appreciated. Thanks.
