How can I remove white space around inline content?

I have Easy Fancybox set up on my site to display some inline content when you click on a link. However, it displays a lot of white space on either side of the image when the lightbox pops up. See this screenshot: http://i59.tinypic.com/2ut0zeb.jpg.

The settings are set to this: http://i60.tinypic.com/24mgyf9.jpg

How can I set the Fancybox to remove the whitespace at the sides and to trim it to the edges?

Thanks
