Next GEN Gallery – Flash Slide Show/need to alter size

I am trying to enable the flash slide show utilizing the JW Image Rotator under ‘Options’ within gallery settings.

It works, however, my default size for the slide show is set in options to 400 x 300 and my flash slide show is a very odd vertical size cropping out most of my photo.

I am not a web designer or know much about coding, however, I can change css coding if given a specific line of code and told exactly where it goes. I’m not sure if this is a css problem or what. I can enable the regular slide show fine (although can’t seem to center it). The main problem is with the flash slide show. You can see it here.

Thank you in advance!
