Horiz Menu

Is it possible to have 2 images one for the menu and one for rollovers and have actionscript determine which buttons I rollover?

For example - I have a menu that I created in a graphics program with a background color, 7 buttons (HOME, ABOUT, etc) with text, and separators. I also have a rollover graphic with a different background color with the same 7 buttons with text, and separators.

Is it possible with actionscript, say I rollover HOME and it displays the rollover graphic but only over HOME and the same for the other buttons? I thought it would be easier using two images instead of separating the buttons etc. Thanks
