############################# Quick Start Installation #########################
// put this file in a directory that contains your images
// the slideshow should now work...
############################# Customized Installation #########################
// Q: how do i add image comments/descriptions to the slideshow?
// A: make a file (e.g. pics.txt) that contains the image names and descriptions
// place each image name and description on a new line separated by a semi colon.
// an easy way to do this is type
// ls *.jpg > 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.
// NOTE: for security, you can only access directories within the same level as
// the phpslideshow.php script...
// eg http://your_url/phpslideshow.php?directory=dog_pics
// eg http://your_url/phpslideshow.php?directory=cat_pics
// eg http://your_url/phpslideshow.php?directory=extra/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
//
// 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 <? php tags.
// also, the // at the beginning of the line need to e removed.
//
// 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 but the ";" is a MUST!
// point your browser at the script and voilla!
