How to display 100 categories?

I have 100 categories in my blog. I want to display all categories under each pages (=above footer) and looks like horizontal menu. May someone can help me about the code for this purpose? Here is my blog: http://www.car-pics.net.

Thanks for your kind help.

Best regards,

 

IN THE FOOTER PART OF THE FILE
<ul class="footermenu">
<?php

wp_list_categories("title_li=");

?>
</ul>

Style.css
.footermenu{padding: 0px; margin: 0px;}
.footermenu li{display: inline; padding: 10px;}
.footermenu a{font-size: 14px; color: #ffffff ;}

NEED ANYTHING ELSE?
