1) Unzip the Frontpage Slideshow Standalone version.
2) Navigate to the slideshows folder in the unzipped folder.
Frontpage Slideshow Standalone -> fpss -> slideshows.
3) Create a copy of the demoslideshow folder and name the copy myslideshow.
4) Upload the fpss folder and all the subfolders and files to the root directory of your server.
5) Create a snippet and paste the code below (note: make sure you have the correct absolute path to your server)
<?php
// START of "Frontpage Slideshow" settings
$nameOfSlideshowToDisplay = "myslideshow";
$URLofyoursite = "http://www.example.com";
$AbsoluteServerPathofyoursite = "/home/example/public_html/";
// do not edit below this line
include_once($modx->config['base_path'].'/fpss/mod_fpslideshow.php');
?>
6) Once you have the snippet made and folders uploaded, insert the snippet into the location of the document you wish to see slideshow appear. From there make your own modifications to the slideshow.
