WPG2 install - Spacing Thumbnails.

Hi,

I've got Wordpress and Gallery already installed, but getting the siriux theme to fit properly inside the wordpress page is just driving me crazy. I'm not the best at php (just basics). Basically I want to get the thumbnails to space evenly inside the page. Seems simple enough, please let me know if you can do it and how much it would cost to get it done.

See the page here: http://www.nickyu.com/?page_id=23&g2_itemId=256

You can see its integrated no problem , but the spacing is off. Please help!
