How can I...

make a simple portfolio type of site to embed INTO Gallery? It seems everybody is embedding into a DB driven cms but I have no real need for a cms. I just want to add some features that could embed into Gallery instead of the other way around. I did check out PixelPoets tutorial. That has me started in the right direction. I dont know php that well but I did try this unsuccessfully: I created a index.php in the main root.

<?
require("/gallery/html_wrap/wrapper.header.default.php");
require("/gallery/html_wrap/wrapper.footer.default.php");
?>

...but I got this error.
Warning: main(/gallery/html_wrap/wrapper.header.default.php): failed to open stream: No such file or directory in /home/deltabo/public_html/index2.php on line 2

Fatal error: main(): Failed opening required '/gallery/html_wrap/wrapper.header.default.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/deltabo/public_html/index2.php on line 2

Am I getting in over my head? or is there a good tutorial around to do this? I wish to achieve something like http://www.chadmallory.com/personal/me/
