Another question...

All right, Flash Gurus. I'm more calm today and I have another question for you!

How would I go about, or could you please point me to a tutorial on, creating a rollover in Flash? The specifics: when the user rolls over a text button (I have this part already) an image (a large one) on the left side of the movie changes..

Does this mean I'll have to make the image part of the button, and just make the button really large? Or is there a better way to do this in actionscript?

Thanks for any help!
