Rollver image - swap another image - help please!

Hi there,
Again I have a basic FLASH script problem. I would really appreciate help if someone has time. Can someone please help me out with the simple fla script for the following scenario:

  1. 4 small images on the left. When mouse rolls over each one a separate larger image on the right changes. (similar i guess to a gallery with thumbnails).


  1. If user likes what they see on image on right - they then click on that small image which takes them to a new page.

I can not for the life of me find the simple example. I have tried (using movie clip with four different frames and stop on each one - trying to call that from main - but then get stuck.)
I’m really new to flash - really enjoying it - but getting stumped along the way!
