Using the "behaviors" window, you can make your page more dynamic. You can use events (Mouseover, Mousedown, etc) to make stuff happen.
1. Using Fireworks
create a button and insert it into a new dreamweaver document called behaviors.html. 
2. Select the image, and get the behaviors window. (Choose Window->Behaviors).

3. Click on the plus button. Choose Set Text, Set Text of Status Bar. Type in the text you want to appear in the status bar when the user moves the mouse pointer over the selected item.

4. When you click on the image in Dreamweaver you should see the event listed in your Design, Behaviors panel.(OnMouseOver means the user passes the mouse over the selection)
5. To test out your behavior. Save your page and preview it in Explorer. Did the message ever leave the status bar???
6. Now you need to add another action that will get the words out of the status bar. You have triggered the event now you need to stop the event when it moves away from the image. You need to add a blank text box. Select the same image. Click on the + sign. Select Text, Set Text of Status Bar - leave the text field blank. Because the event defaults to OnMouseOver we need to change. Click the down arrow and you will see the pictures below. Choose onMouseOut (the mouse pointer has moved away from the selected item)
7. Click on the image below to see another type of behavior

8. You may want to show more Events. This should open up more choices for you.

Add 4 new behaviors to your behaviors.html page. On this page - explain in words each behavior you have chosen and how it works. Test each of them out in Explorer, Firefox and Safari. Email me the results.
Save your project and create a link from your home page.
To do more: Create a dreamweaver document with 4 layers call it morebehave.html. Put either an image or text in each layers. Give each of the layers a name. Using a book, on-line help or experimentation figure out how to make the layers so that the user can drag them around in any direction. Figure out how to constrain the type of distance or area or direction in which the layer can be dragged. Make sure you put a link on your home page
