Title header not top centered on page

I tried this in the header page for the title to only display on the home page and that didn’t work.
<?
if (is_home() && strpos($_SERVER[‘REQUEST_URI’], “/page/”) === false) {
?>
<center><img src=”http://jds-productions.com/wordpress/Images/HowGreen.png&#8221; border=”0″ alt=”How Green” width=”600″ height=”50″ /></center>
<?
}
?>
Right now I have it written in the text, which it doesn’t align because of the sidebar.
<img src= “http://jds-productions.com/wordpress/Images/HowGreen.png&#8221; alt= “How Green” style=”text-align: right; margin-left: auto; margin-right: auto; margin-bottom:10px;” width=”600″ height=”50″ />

Any suggestions?
