Select a tune from those that are listed on The Changes page and follow its link. When that tune's page loads you will nearly always find that the page includes links titled "Printable GIF image" or "Printable JPEG image".

When you press those links, you will see yor browser will launch a page that displays a page from that arrangements score. If you right click (Windows) or control-click (Mac) on the score image you will find that a menu popups at the location of the mouse pointer. On that menu, a command to "Save Target As" or "Save Link As" will be displayed. If you select that command, a Save dialog will be brought up which will allow you to select the location in your computer's file system where you wish the downloaded score page to be stored.
