Change layer image / embed options

[deca]

Hi!

I have to ask you 2 thing:

1) How can I do this (change image) in IE?
document.myLayer.document.myImage.src='newImage.gif';

2) I have this object into a page:
<embed name=&quot;sound1&quot; src=&quot;sound1.wav&quot; hidden=&quot;true&quot; autostart=&quot;false&quot; loop=&quot;false&quot; volume=&quot;100&quot; mastersound>
How can I tell the embed object to ignore the &quot;unable to play wav sound&quot; error that is called when the audio driver is already used?

Thanks & bye!
