Script edit so my flash logo will work.

Hi iv made a flash logo for my site the old logo is a image this is how it is shown in the layout

<script>
if (document.getElementById("logo-div").style.backgroundImage.indexOf("images/null.gif") > 0){
document.getElementById("logo-div").style.backgroundImage = "url(this is were the logo was and i want the flash bit to go)";
}
</script>

How will i make that so it shows my flash file not a normal image file if it can be done.

Thanks in Advanced.

If i put the in the rong part of the forum please move to the right part thanks.

 

Instead of the image you put filenamehere.swf, as far as i know.
