pics.txt in linux or
// dir *.jpg > pics.txt in dos - you will need edit this with notepad/vi to clean
// out any extra stuff that dir puts in there and to add the semi colon and
// description.
// the slideshow should now work including comments...
//
// Q: how do i give each directory of images it's own page heading?
// A: place a file called heading.txt in each directory. place the page heading
// on the first line of this file.
//
// Q: how do i use one slideshow for multiple different directories of images?
// A: all you need to do to enable this is to call the script and pass it the
// directory path.
//
// for example:
// pictures_directory -> phpslideshow.php
// -> dog_pics
// -> cat_pics
// so you have a directory called pictures_directory that contains your
// phpslideshow.php and two directories containing pictures of your pets...
// in order to access the shows:
// http://yourserver.com/pictures_directory/phpslideshow.php?directory=dog_pics
// http://yourserver.com/pictures_directory/phpslideshow.php?directory=cat_pics
//
// if there were images in the pictures_directory, you'd see them like this:
// http://yourserver.com/pictures_directory/phpslideshow.php?directory=cat_pics
//
// these three examples will run phpslideshow but each one will load a different
// set of images and descriptions located in the directories shown
//
// NOTE: for security, you can only access directories within the same dir as
// the phpslideshow.php script...
//
// Q: how do i use phpslideshow.php in my existing web page or html template?
// A: change the $standalone variable from true to false.
// what this does is removes the html page headers and footers and only prints
// out the phpslideshow table...
// to use this in an existing php page, use the following line:
// include("phpslideshow.php");
// don't forget that this is php code so it needs to be inside the
//
//My cool PHPSlideshow
//
//
// EXAMPLE pics.txt file
//
// greg.jpg;Me
// dog.png;My dog John
// cat;
// tux.jpg;My friend Tux
//
// NO BLANK LINES either!
// as you can see, not all pics need a description
// point your browser at the script and voilla!
