How to play till next picture?

1

Hi,

I am AS newbie and would like to ask how to do this in Flash MX:

  1. I have 4 differents still images incorporated into mc-s, pict00_mc - pict03_mc.

  2. I fade these image mc-s into each other over the timeline using alpha.

  3. I have a play and a stop button too, to controll the animation.

  4. I would like to achieve that anytime I press the stop button, it should stop not at any intermediate point (e.g. in the middle of the alpha animation) but ALWAYS at the start ofthe next picture with 100% alpha.

How to achieve this?

Thanks
