AS 2.0 Loading/changing images depending on selection (example .fla included)

Hello,

I would like to have sort of a menu to the left of the screen (roughly 8 different ones).
Then each menu will display from 3-8 options on the right hand side. Each option has a picture and a little description.

My question is, how can i change the menu image on the left to the image of the option selected on the right (after they have chosen their selection)

So for example:

imagine this is done all by images, not text.

My menu is 1 2 3 4
user presses 1 and is displayed with the options a b c d
they select d

the menu is now D 2 3 4

I have included wha ti’ve got so far in a .fla

thank you very much for any help on this. I’m not sure the most correct way to do this. I didnt want to load the images from a database because i’ll only have up to 8 options max…

here is my little .fla i made for it…
