[Plugin: NextGEN Gallery] slide show border issue

I have the slider set up on the home page but there is a border around the left and the top but not the right and the bottom. Is that normal? Also I am trying too get some consistency in the images in the slider but even when I scale them the same width they don’t match or if I scale them the same height I still see discrepencies (not referring to the scale of the other dimension but the one that is the same). Thank you. http://184.173.253.217/~tbfa/wp-admin/
