i've already installed zenphoto and created a couple of albums but don’t know how to I make the photo slide show created become one of my website pages i.e. accessed by a hyperlink on the navigation bar?

The slideshow gets the data which album to display submitted via a form within album context. You can make a form submit manually, too. Take a look at the printSlideshowlink() function's form of the slideshow plugin what needs to be submitted.
