Slideshow JS adding margin-top

I’m trying to use NextGEN Gallery to have a homepage slideshow on my website. I am using the latest version of the Autofocus theme by Allan Cole/Theme Supply Co and on the homepage there is some JS code associated with the slideshow (I think) adding -355, 55, and 57 pixels of margin to the top of the slideshow image for only some of the images. Each will have one of the different dimensions and some of them have no extra margin and display just fine. I can’t find any code in the plugin that would be doing this. Only by adding an !important line of css to my style.css file can I make this problem go away, and obviously this is not ideal. Any ideas where this extra margin is coming from?
