Replacing homepage logo with flash slideshow

[galactic]

I want replace homepage_logo.jpg image on start page with flash slideshow. The code below is what I wanted to add in place of homepage_image:

 

<object type="application/x-shockwave-flash" data="./slideshow/slideshow.swf" width="530" height="226">
<param name="menu" value="false" />
<param name="wmode" value="transparent" />
<param name="flashvars" value="xml=./slideshow/slideshow.xml&dir=./slideshow/" />
<param name="movie" value="./slideshow/slideshow.swf" />
</object>

 

I uploaded slideshow folder containing images and xml filers into the \modules\editorial folder, and tried to add code into Home text editor: Back Office > Modules > Home text editor, via "Insert/edit embedded media", code was saved in editor, bit it don't appears on page. Also tried to add code via"Edit html source" editor, same result.

So this simple task not so easy to get in Prestashop, I just wanted to make simple mod without hacking the core files, but I don't know how to achieve this.
