I agree that using another web design software with Shozam is the easiest way to get the code needed. As the last comment noted, you can make additional pages to link in but you can also modify the page created in Shozam. Keep in mind, every time you regenerate a gallery or album the page will be recreated and you will need to change it again. The only way around that is to make the modifications in the Shozam program where you can add HTML code. The trick here is to create the code using something like FrontPage or Expressions and cut and paste the code into the Shozam design. Here is a link as example:
http://www.gallerypg.com/WebGallery/Landscapes%20Near%20and%20Far/index.htm The additional information at the top and bottom were designed in FrontPage but then copied into the Shozam program so if I modify the album or gallery, I still have the same information top and bottom. My index page www.DSDigitals.com has also been changed in FrontPage but because this is a static page and will not change regularly, I did not incorporate it in Shozam simply made the changes by opening the page created in Shozam in FrontPage and modified it.
