Switching between images...

[Ken Ray]

Guys, guys... don't forget that Rev automatically senses for the rollover
when you set the "autoarm" to true. So set the 'icon' of the button to the
first image, the 'armedicon' of the button to the second image, turn the
autoarm on, and there's no script to write!
