I put the jquery code in 4 places: header.php, image.php, page.php and single.php. For the main page to be honest I can’t remember which one php page mod got it on the main page in the center but it did. I had to add some dots after the description of my site though to get it in the position that I wanted it.
I don’t really have time to tell you exactly where I put the code on all 4 pages. Try experimenting with it and if you figure out which php page controls the main page and can’t figure out where to put the code I’ll tell you where I put it on that one page.
