Arranging Additional Images

I have added a new theme to my site and one of the things I cannot seem to solve is regarding the additional images. 90% of my items have three additional images. I have zen light box and I think image handler installed. What I want to do is make them sort of line up more neatly toward the left side. Right now they are spaced way too far apart and it looks unorganized. Example:
http://www.polishpotterystore.com/shopping/index.php?main_page=product_info&cPath=10_32&products_id=884

I modify my stuff myself so if I need to add code, give me specifics. Thank you!

You could give them a width, like this:

#productAdditionalImages {width:300px;}

It's been a while since I've used Image Handler, so I don't remember if it works with additional images, but those images aren't optimized and are big enough (file size) that they slow down your page load.
