Book mark button/social networking where to place?

Hi,

I have seen the modules for social networking and one of them by swguy, that I installed is fine, but on hover of allot that I see the bookmark button shows the sites and more in a drop down, but this one customers are sent to another page.

Basically what I am asking is, that add this which is a site that generates the bookmark button and others for this, has a snippet of code that is to be placed within the header tags of the your site and that’s it done?

Can I do this with Zen Cart and which file can I add this to get it to the top right of the page?

I hope someone can advise as this code can have analytics combined so it tracks all in this one piece of code?

thanks
Paul

I forgot to give you the code that I need to place,

<a href="http://www.addthis.com/bookmark.php?v=250&pub=bruceter" onmouseover="return addthis_open(this, '', '\[URL]', '[TITLE]')" onmouseout="addthis_close()" onclick="return addthis_sendto()"><img src="http://s7.addthis.com/static/btn/lg-bookmark-en.gif" width="125" height="16" alt="Bookmark and Share" style="border:0"/></a><script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js?pub=bruceter"></script>

Please can someone help, I know it says that it needs to be placed between the header tags, but where are they in zen cart and can it be placed at the top right of my site?

thanks again
Paul
