First all you do there is sign up for a Free Account at VHTV. Then you have the option to hide the preview bar. If that's too much then there's an easy way as well. Just right click with your mouse between two images on the divider and select Inspect Element. A page will show at the side and go to the top on the Tree Menu and Delete the Element "Screen Holder" and the Preview Bar will vanish out of sight. It will stay that way as long as you are on the page. Once you close the page you'll have to go through the same process for the Preview Bar.
