Where can I find a straight-forward tutorial on creating ActionScript 3.0 fading rollovers that assumes you know nothing about Flash? (CS5)

I am a retoucher and when I post my pictures on my website I want visitors to be able to roll over the picture and have it fade to the original unretouched version and when they move the mouse away I want it to fade back to the retouched.

In my search I have found guides on deviant art for Actionscript 2.0 and fo开发者_Python百科r ActionScript 3.0 but the AS 3.0 one i found does not include the fade effect i want to achieve. Google has also helped me find some tutorials but they are too advanced for me to understand. If someone could show me where to find a beginner's tutorial using flash cs5 on this that would be great thank you!

Question,

So you plan to use external images and have them dynamically loaded making it easy to change them at a later date or do you plan to have a swf with the images embedded?
