Step 2
Add the mouseover image:
a) Open the Image properties and select the Events page.
b) Select onmouseover and set the action to Set Image.
c) Specify the Filename of the mouseover image.
In WYSIWYG Web Builder most objects like images, shapes, form controls and pages have Event Properties, which allows you to easily add actions to object events, like onclick, onmouseover etc. Predefined actions include: Show, Hide, Move, Set Image, Play, Pause, Stop and Javascript function. Multiple events can be assigned to a single object.
Step 3
If the mouse moves out of the image area, we want the original image to reappear.
a) Open the Image properties and select the Events page.
b) Select onmouseout and set the action to Set Image.
c) Specify the Filename of the mouseout image (this is usually the same as the original image file).
Step 4
To play a sound we will use the Audio object.

Please be aware that not all browsers do support the same media formats! See the information in the help for more details about this.

Click Insert -> Media -> Audio on the menubar.
Open the object's properties and select a sound. Set the type to 'HTML5 audio'.
Disable Autostart and uncheck the Visible property in the Object Manager so the object will not be displayed in your page.
In Property Inspector lookup the ID of the object, if this is the first Media Player object on the page this is usually called 'MediaPlayer1'.
Step 5
Now we're going to attach the sound to our rollover image.
a) Open the image properties and select the 'Events' page.
b) Select onmouseover and set the action to Media Play.
c) In target select the ID of the Media Player object: MediaPlayer1.
If you like you can also stop the sound when the mouse moves out of the image area:
a) Open the image properties and select the 'Events' page.
b) Select onmouseout and set the action to Media Stop.
c) In target select the ID of the Media Player object: MediaPlayer1.
