Tween for BMP transitions

[Guest_imported]

Example:
Two BMP's created in Photoshop.
Frame 1 is a green leaf, Frame 2 is a red leaf.
How do I tween the two images so that the green leaf gradually turns red?
I can get art created in Flash to do this, but not the imported Photoshop files.
Any help is appreciated.
Thanks.

Import each bmp on it's own layer. Add motion tween to both of them going from alpha effect value of 100% to 0% on one of them, while you go from alpha 0% to 100% on the other one!
