Want a simple slide show with fade transitions between images

want buttons:
play - images fade in and out automaticaly
stop - easy enough ( no help needed)
forward - fades to the next image
backward - fades to previous image

as simple as possible

thanks

i want to do it with action script so that it will be easier to manage in the
future, i dont want to many frame tweens because it just gets messy with the
volume of images i have. just simple cut and paste of code on MC's and butons

BTW, how were you thinking of doing it with the masks?
