To use the Swap Image action:
1 Choose Insert > Image or click the Image button on the Object palette to insert an image.
2 In the Property inspector, enter a name for the image in the leftmost text field.
The Swap Image action still works if you do not name your images; it names unnamed images automatically when you attach the behavior to an object. However, it is easier to distinguish images in the Swap Image dialog box if all of the images are named beforehand.
3 Repeat steps 1 and 2 to insert additional images.
4 Select an object (generally the image you're going to swap) and open the Behavior inspector.
5 Click the plus (+) button and choose Swap Image from the Actionspop-up menu.
6 From the Images list, select the image whose source you want to change.
7 Click Browse to select the new image file, or enter the path and file name of the new image in the Set Source To field.
8 Repeat steps 6 and 7 for any additional images you want to change.
9 Select the Preload Images option to load the new images into the browser's cache when the page is loaded.
This prevents delays caused by downloading when it is time for the images to appear.
10 Click OK.
11 Check that the default event is the one you want.
If it isn't, choose another event from the pop-up menu. If the events you want are not listed, change the target browser in the Events For pop-up menu.
The secret of life is honesty and fair dealing. If you can fake that, you've got it made.
