Hello,
My name is Adam I have been following this site for a while for help and advice but I have got really stuck and have decided to join for some guidance. I am using Atahualpa and am stuck on trying to use a different background image on just one page and use my default one on all other pages.
I really dont know where to start on this so any help would be much appreciated.

do a forum search as your first step. this question has been answered a number of times

do it with CSS
body.home {background-image: url(...);}
body.page-id-24 {background-image: url(...);}

Thanks for getting back to me, I have tried the above methods but I don't know where to place the code? Do I place it in the CSS.php in the atahualpa folder? if so where in the file do i place it?

you put it in teh theme option ATO->Add HTML/CSS Inserts->CSS Inserts - then it is a theme option and you don't have to worry about editing the code on the next upgrade. Avoid editing the theme code, almost everything can be done via the options.

I've tried this, and I can't get it to work at all. I used Firebug to find out where I would want to change the middle & footer background images as well, but I'm not having any luck.

Here is the code I used:

body.page-id-2 {background-image: url("/wp-content/themes/atahualpa/images/header1.jpg");}
footer.page-id-2 {background-image: url("/wp-content/themes/atahualpa/images/footer1.jpg");}
middle.page-id-2 {background-image: url("/wp-content/themes/atahualpa/images/main_bg1.jpg");}

I also turned off the right sidebar on that page, but what am I missing?
