Background Image Question

I have been searching through forum posts, blog posts, expertzzz posts; I even messaged one of the expertzzz whom from allot of posts I am led to believe I can trust.  I have still been unable to find an answer to my inquiry so I decided to go ahead and post this in the hopes I can be at least led to another place to find my answer if not provided it here.

My dolphin site is coming along nicely I believe.  My graphic designer and I have been working hard to come up with a site thats attractive and maintains functionality.  I hesitate posting the url here because oft, i see the urls that are postd here show up a short time later as "hacked".

Once I can afford the security fixes offered on expertzzz and I have some peace of mind, maybe I will share it with you publically.

What I am trying to do is assign different background images to different pages....

Currently using general.css I have assigned one of my background images to the index or homepage.  It looks stunning!  I have (thanks to craftstorez on expertzzz) added a mall functionality and for it I woudl like to change the main layout of the site too.  If you or are not failiar with this mall script; it gets called in through javascript and an iframe into the main layout through a page called shop.php... that being said.. shop.php (which shows a call to index = 28; ) still calls up general.css as its design layout and what I would rather have it do is call up general2.css...  there are other pages I want to do this to as well but this is my main priority as of now..

Can someone tell me what I need to change in order to get this done.  I even looked for a paid mod, but to no avail as all i could fine were template switchers for the users (like would be used in Joomla frontend).  I don't want to say I am desperate for a piece of advice, but I am willing to say I am frustrated at this point.  I am new to webdesign and webmastering, teaching myself things as I go.

Anyone got advice?  If you absolutely need to see the url I could probably provide it, but like I said I have worries of security breeches.

Thank the sweet heavens for Mr. Powless, he is an angel of mercy!!  I asked and I did receive.  He was fast, courteous, and got straight to the point!!

Thanks again man!!!

Yes the answer was?

Not very fair not to share after asking here ;-)

Sorry all.. Here is a copy of the response I got from him.  I swear my head isn't on straight lately as I have burried myself into getting this site working, looking, and functioning as I want it to....  My appologies!!

turn off permalinks in admin/settings/permalinks
goto url you want to edit. look at php file it uses
open php file and look for(add if not exists)
$_page['name_index'] = 57;
$_page['css_name'] = 'ray_chat.css';

57 is the html file it uses
these are found in templates/tmpl_uni/page_57.html
To make one add the following:
__include _header.html__

<div class="clear_both"></div>

__page_main_code__

<div class="clear_both"></div>

__include _footer.html__

Its pretty simply put together if you can get your head around this lol
