Have a 3 column fluid layout (%) . I cannot find a way to center an image gallery in the middle column. Tried everything a newbie can do with no success. Any suggestion? Thank's

[CODE]
<div id="middle"
<div ???>
<div id="gallery">
....pictures
<div>
<div>
<div>

That's not enough code to figure it out. You'd need to post a link to your page. Do you have no CSS?
