I've managed to fix this little problem.

The source of the problem is the template file called spacer_open. It has the class page in it which causes the multiple bg repeats. To fix it, create a .page2 set in the css. Transfer everything into that except the picture. Make sure you edit the spacer_open template classes to page2. Then go to your header, find the spacer_open tag at the bottom and replace it with something like this:

<!-- spacer_open included by gbboy (pgamers.org) -->
<!-- open content container -->
<if condition="$show['old_explorer']">
	<table cellpadding="0" cellspacing="0" border="0" width="$stylevar[outertablewidth]" align="center"><tr><td class="page2" style="padding:0px $stylevar[spacersize]px 0px $stylevar[spacersize]px">
<else />
	<div align="center">
		<div class="page" style="width:$stylevar[outerdivwidth]; text-align:$stylevar[left]">
			<div style="padding:0px $stylevar[spacersize]px 0px $stylevar[spacersize]px">
</if>
<!-- end spacer_open -->

Hope that helps anyone else with the same problem
