Update - I have found that
Code:
<div align="right">
$ad_location[ad_header_end]
has allowed me to place the ad to the right side - but "center" does not position it in the center as the banner above it is - ie it is definitely moved toward the center of the screen but not centered off anything that I can see and does not work with the centering of the banner above...

Fixed it this way:
1) leave header alone
2) put this in ad_header_end
Code:
<div align="center">
<img height=16 src="http://www.archeli.com.au/forums/images/arcHELI_branding/infolayer-padding.gif" border="0" >
<ad what="zone:13" /><ad what="zone:12" />
I used a transparent object the same width as the main logo and when this adds to the other two items they centre the same way that the obejcts above do!
