[Plugin: WordPress Gallery Plugin] Change Gallery width

I created a gallery (http://en.support.wordpress.com/images/gallery/ and http://ww.wp.xz.cn/extend/plugins/gallery-plugin/faq/), but you can see here: http://daviddoria.com/?gallery=pictures-2 that the sidebar widgets got pushed to the bottom of the page, instead of being on the right like they usually are (http://daviddoria.com/?cat=12). I see options for how wide each image is, etc, but I don’t see an option for how wide the gallery itself is. Is there a way to change this?

I tried to change the content-main width, and the gallery indeed gets smaller, but the side bars are still pushed down.

Thanks,

David
