How can I build a slider like this?

hello,
I´m going crazy because I´ve to finish a project in two days and still need to build a product slider. there was one I´ve found in the internet as swf. It´s almost like I need it to have. SO if you push the next/prev button the images slides exactly for one image. in that example the movement looks a litle bit strange so it would be nicer if ther´s an easing or sth. similar.

does anyone of you know how to build that or better where to get an example? My flash isn´t that good to build it by myself…
