Can you help me with some slideshow code?

programming flash
1

How can I stop this slideshow flicking through the images automatically? I just want it so that people click next or previous and then it goes to the next or previous.

If you want to see what its doing now, go to www.nmphotography.co.uk/main4.swf and its the calendar on the contact page.

Thanks in advance
