Need drop down script

I am looking for a script that will do the following:

I have a graphic in the middle of a page, below it are several more links/graphics. I want to be able to click the main graphic, and it will show the other links (or they slide down), if clicked again it hides them. It needs to move the rest of the page down/up depending on what one is clicked so it doesn't just leave a blank space on the page. The links are currently in frames.
