From just dinkin' around in Style Manager, which you, too, are empowered to do, in the header template if I pop entirely the $stylevar[right] td, then change the remaining td tag align=$stylevar[left] to align="center" that puts the logo in the middle. This is just a how-I-did-it and may be totally unrecommended by anyone knowledgeable in vB. There is an extensive, well-put-together write up on Styles & Templates in the vB Manual.

In the header template:
Pop the right td tag ->
	<td align="$stylevar[right]" id="header_right_cell">  … </td>
Change remaining left td tag from:
	<td align="$stylevar[left]"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a></td>
Change to:
	<td align="center"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a></td>
