I am trying to get an interactive table image in my header, I want it to look similar to the one on expressionengine.com.

Basically, I want an image to: 1. look like a menu 2.have buttons that, when clicked, just change the top part of the image/menu 3.I don't want the buttons to link to other pages, I just want them to cause behaviors inside of that image. If my explanation doesn't make sense, take a look at expressionengine.com

So, I was told that expressionengine used jquery to do all of this. I wanted to know the following.

Would jquery work to make that menu?
How do I use Jquery/javascript with dreamweaver/fireworks?
does javascript work on images? If so, how do you apply it to images
Which jquery tutorial would be best for showing me this technique?

Thank you so much
