How do I use php Include?

something4ken

I'm trying to use PHP INCLUDE to place Zenphoto blog below my main navigation. But I got this error.
Warning: Cannot modify header information - headers already sent by (output started at /home/content/s/o/m/something4ken/html/jln/blog.php:8) in /home/content/s/o/m/something4ken/html/jln/blog/index.php on line 9
...

here is the URL: http://www.kenfxstudios.com/jln/blog.php

and this is the way I called the file:
<?php include("blog/index.php"); ?>

zenphoto works fine without the PHP include though.

Please help

This tutorial helped me quite a bit. It's specifically written for a WordPress/ZenPhoto combination, but you might just find something useful in there.
