I used the above suggestion, but changed the code from the author to this

PHP Code:

#vbulletin_logo {
background-image: url(http://www.YOURWEBSITE.com/images/logo.png); 
display:block;
background-repeat: no-repeat; 
text-indent:-9999px;;
position:relative;
min-height:65px;
} 


The mid-height values and site values you can change as needed.
