The page http://www.thyrfing.com/ does not have a scrollbar because it is a frameset which either doesn't provide one if the content is small or you can add noscrolling. If you make the viewing window of thyrfing smaller than the centre image scrollbars will appear.
Your page has more content including Upcoming Shows below the images so a vertical scrollbar would occur for most viewers.
If you put just the main image in a frameset and used it as an entry link like thyrfing then you would not get a scrollbar. See

where the top frames do not have a scrollbar even in IE, but the bottom frame has one because there is lots of content.
Or just centralise the image vertically and horizontally. See

Firefox never provides a vertical scrollbar unless it is required but IE will provide a dummy one which you cannot avoid except by using a frameset or javascript.
Code downloaded to my PC will be deleted in due course.
