Best way to do a Flash audio slide show

Hi there…
I would like to built a flash audio-image gallery like this one at http://www.nytimes.com/interactive/2007/09/01/magazine/20070802_PARTNERSHIP_FEATURE.html
When you rollOver over the audio timeline a small thumb appears which is also a point at this timeline an you can click it…It is devided in different sections so you will be able to jumb to another section.
My question is should I try to trigger events to bring up different .jpg files at different points in the flash audio? Is this possible?
Or could you give me a light on how i could start on this.
Thanx…
