Ading buttons to this slideshow?

1

hi,
I found a really cool dynamic slideshow in the internet. the fla is only one keyframe with as…

it works great, but I have no idea to add a pause/play button , so that it pauses at one point and starts at the same by clicking play. also I want to add a next and prev button, but I have no idea how that functions could be like…

can anyone help me?

heres the code:
