Present image on rollover

I posted a message with several questions yesterday.  I've been able to figure 
out all of them except for one.  Here's the web page I'm working on: 
http://cdkarts.com/portfolio.html.

 What I'd like to do is create a Flash application that displays a different 
image in the box to the right when the viewer rolls over the various menu
items.

 I'm on a crash course learning Flash and Dreamweaver right now with no 
previous experience in either program.  I don't expect anyone to do the coding 
for me; but I would be grateful for a few tips.  Even directing me to the right

section of the help files, giving me the names of elements/commands I need to 
research, etc. would be very helpful.  I want to learn how to do it myself - I 
just don't even know where to start.

 Thanks.

I've created a sample that you can scrutinize as far as what's been done to 
have images swapping for button rolloovers.  You can download it here:

 It's great that you want to learn this stuff yourself... that's what I did/do.

 There's years of learning ahead of you, have fun with it--I know I'm not done 
yet.  

 The best place to start in my case was to dive in and try to design something,

which is what you have done so far.  I can't say it's the best place to start, 
but it can't hurt (Myself, I hate reading... doing is more fun).

 I wish I could recommend a good book, but the only one I ever bought 
(recently) was Essential Actionscript 3.0 and my first attempt to make use of 
it resulted in me deeming it to be a good doorstopper or paperweight.  There 
was a posting yesterday where some people recommended what they consider to be 
good beginning books, so maybe you'll find it without much problem (today... 
avoid the Monday rush of new postings).

Ned,

I can't thank you enough for the file!  It is the easiest way to learn (by
doing).  I'll dig in and see what I can do.

Best,
