How a custom gallery with PHP functions in wordpress page

Hi all,

Ok so the goal here is to include this gallery in a wordpress page. If I can get this sorted I will be using it to create the “Client login” pages.
http://jwphotographynz.com/customuploads/client/test/index.html

What I have tried:

1)Using Kimili Flash embeder plug in. Using MANY variations on some thing like this
[kml_flashembed movie=“http://jwphotographynz.com/customuploads/client/test/host.swf” base=“http://jwphotographynz.com/customuploads/client/test/” height=“600” width=“1000” /]

Problems:

It seemed VERY random as to wether it would work or not. For example adding text to the post as well would break it. Would work for 2 refreshes and not on the third on the same computer same browser. Also I lost functionality from the slide show (shopping cart etc)

2) Using allow php in post plugin for wordpress. This was a compleat stab in the dark as I know very little PHP. Tried variations of

[php debug=1]

require_once (‘/Pages/Newton/index.html’);



[B]Getting this back:[/B]
Fatal error: Call to undefined function require_once () in /home/jwphotog/public_html/wp-content/plugins/allow-php-in-posts-and-pages/allowphp.php(110) : eval()'d code on line 2


[B]What I do NOT want to do:[/B]
1)Use a different slide show generator, This one gives me all the functionality I want.  Of corse if some one else can suggest a lightroom plug in that will out put slide shows with paypal shopping cart, password protect, highly customizable content. I would be open to suggestions.
2) Link directly to the index.php of the slide show.  I really want to retain the aesthetic/links/etc of the wordpress theme while viewing the gallery.


Wow . . . . sorry that was long!  Any feedback is appreciated, im a beginer but im like a dog with a bone with this stuff so feel free to throw ideas around :)
