OK, remove that declaration from the stylesheet...

There is one other option that WILL work, but it will require you to change the WIDTH of your logo (smoosh 2.png) (and your mainwrapper width) to 776 pixels.

(By the way... your logo NAME - smoosh 2.png - has a SPACE in it... You should re-name it to smoosh2.png (no letter spaces).

When you change smoosh 2.png to have a width of 776px, find the following in the stylesheet...
Code:
#mainWrapper {
	background-color: #ffffff;
	text-align: left;
	width: 750px;
	vertical-align: top;
	}
Change to
Code:
#mainWrapper {
	background-color: #ffffff;
	text-align: left;
	width: 776px;
	vertical-align: top;
	}
Then, find this:

Code:
#headerWrapper, #contentMainWrapper, #logoWrapper, #cartBoxListWrapper, #ezPageBoxList, #cartBoxListWrapper ul, #ezPageBoxList ul, #mainWrapper, #popupAdditionalImage, #popupImage {
	margin: 0em;
	padding: 0em;
	}
Then add this UNDER it:

Code:
#headerWrapper {
background-image: url('http://i412.photobucket.com/albums/pp209/smooshboosh/cutebg3.png');
(again, here's the full remote path to that bg image... better to get a local copy, as indicated previously).

NB... you will have to make the following change to your header.php in the language files:

PHP Code:
  define('HEADER_LOGO_WIDTH''776px'); 
The REASON why you must change the width is that the RELATIVE ASPECT RATIO of that BG image is inconsistent with a width of 750px. You must make the width an absolute multiple of the BG image width to get it to TILE properly.
