HELP! Creating image loop

Hey guys,

I’m looking for a little help with a flash enhancement on a site.
**
It consists of the following:**

  1. a text animation that is 50 frames long that will animate first.
  2. 5 images that will animate with a transition and show up under the previous animation.
  3. an animation that is 158 frames that will be used as a transition.

I am having trouble figuring out the best way to make the image mask animate and have another image show up under that transiton.

Any help will be appreciated, thanks!
