Flash Object

I am building a website for someone, and I am using iWeb.

The client wants a closed briefcase on the front page, and then the person viewing the site would click on the briefcase, it would open, and then display all the info.

I have tried some animation programs but I can't seem to find the right one.

Any tips?

Could you just use 2 images, one open and one closed and have it change when you click on it.
