how do I remove the repeating images and boarders from the "Page Background"

[chiselneck]

I am getting repeating page boarders & repeating image when I click on forum postings and reply to post.

In the "Page Background" (Customized in this Style) Extra CSS Attributes, I have the following code:

background-image: url('http://www.myurl.com/images/myimage_04.jpg');
background-repeat: no-repeat;
border: 1px solid #000000;

Anyone have a tip to fix this so the the border does not repeat nor the image?
Thanks
