Hi, Sam -
As noted on the "Home" page, the site is designed for monitors of 1024x768 pixels or above. If you set your browser to "full screen", it should have a scroll bar in the right frame of most of the "gallery" pages, but not have the "middle" scrollbar on the right side of the left ("buttons") frame unless your browser has an extra row or two of 'tools' turned on that most people don't use .
I presume from the text following your signature that you are a professional photographer, so maybe you customarily do have more tools readily available than most of us - which would decrease the height of the window available for web pages.
Thanks for noting a potential problem; maybe I need to shorten the content of the left frame a little. So far, you are the only one out of more than a dozen who have mentioned this.
