Please help me how to print an album on index page. I do not know how to add it. I do not know PHP at all.

I went through the user guide it says

Usage: add the following to the php page where you wish to use these menus: enable this extension on the zenphoto admin plugins tab; Call the function printAlbumMenu() at the point where you want the menu to appear.

I did not understand it. Please help me. where to add the code given on that page
that is

html printAlbumMenu( string $option, string $option2, [string $css_id = ''], [string $css_class_topactive = ''], [string $css_class = ''], [string $css_class_active = ''], [string $indexname = "Gallery Index"], [string $showsubs = false] )

I enabled the plugin in admin section

I do not know how to call a function.
