[Plugin: NextGEN Gallery] Image size

I can’t seem to control the size of the image in my slideshow. I’ve changed every option I can find, but still no luck. Here’s a link to my problem: https://dataltd.com/newsite/dli-7200/ The slideshow is on the bottom in the white area… it is HUGE. Any ideas on what I’m missing? It looks terrible and can never be used like this. Please help!!

Thanks!!
