Add an image after nth result

Hi,

I want to add an image after every nth row of views output. I know that this is possible using views template override. I am overriding views-view-list--viewname--page.tpl.php. The problem is $id is shown for initial results only. Once I click on load more, $id is not shown. I have added this patch also but it works with row classes and not id.

How can I get correct $id in tpl file?

Thanks in advance for help.
