How to get Rollovers side by side in 3 over 3 grid?

Here is my situation:
I have a child theme based upon Expound. My home page has rollover thumbnails that link to their respective pages. However they are all aligned left. What I want is 3 thumbnail rollovers on top of 3 thumbnail rollovers centered on the page. My thumbnails are 235x200px. My website is http://www.cmbgraphicdesign.com
Here is the code I’m working with in my text editor:
<div class=”crossfade”><img class=”regular alignnone” src=”http://www.cmbgraphicdesign.com/wp-content/uploads/2015/02/Featured.png&#8221; alt=”““Featured“”” width=”235″ height=”200″ /><img class=”rollover alignnone wp-image-1154 size-full” src=”http://www.cmbgraphicdesign.com/wp-content/uploads/2015/02/Featured-Roll.png&#8221; alt=”“”””” width=”235″ height=”200″ /></div>

Any help would be greatly appreciated. I want to get my site back to normal soon.
Thanks!
