Slideshow in modern theme not working

Hi,

I’m trying to implement JM_slideshow in modern theme.

So, i’ve copied app and skin. I’ve copied also joomlart folder to app/skin/frontend/default/modern/

I’ve create jmslideshow.xml

<?xml version="1.0"?>
<layout version="0.1.0">
<default>
<reference name="head">
<action method="addCss"><stylesheet>joomlart/jmslideshow/css/jm.slideshow.css</stylesheet></action>

</reference>
</default>

<cms_index_index>
<reference name="header">
<block type="joomlart_jmslideshow/list" name="jmslideshow" >
<action method="set">
<params>
</params>
</action>
</block>
</reference>
</cms_index_index>

</layout>

On CMS home in backoffice, i’ve add in "general" panel :

{{block type=’joomlart_jmslideshow/list’ name="jmslideshow" }}

On frontpage, it seems to load jmslideshow css, and /skin/frontend/default/default/joomlart/jmslideshow/js/jm.slideshow.js

Image is load, but nothing is displayed. What ‘s wrong ?

Think there’s also a bug on image path, i’ve configured /media/slideshow and it point to media/slideshow/media/slideshow/

Here’s the dev adress:
