[Plugin: WordPress NextGen GalleryView] spacing between images and thumbnails

hello,
subject is in the topic’s title.

i would like to have enough space between images and thumbnails

exemple here :
http://nextgen-gallery.com/templates/galleryview/

the plugin works fine but both are sticked together :

any help would be appreciated since the plugin’s author doesn’t seem to be “online” (http://jbmodernwoodworks.com/)

thanks
david
