"no such file or directory" warning message

Hello experts,

I hope you can help me, I don't have enough experience in PHP to figure it out. All I know until now is that "register_globals" is turned off.  

I'm trying to use a free script "phpslideshow". It's only one file and I would like to use it in my own html per "include".

I'm thinking that it might have something to do with the include. When I run the script in a separate windows it works ok.

Here is the complete script with one modification I did - I added the line $directory = $_POST['directory']:


PHP Code:

############################# 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 /b *.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 <? php tags.
// also, the // at the beginning of the line needs to be removed.
//
// Q: how do i make my php slide show appear in it's own popup window?
// A: copy the following lines into the body of a web page
// (minus the leading two comment slashes on each line...)
// <!--begin PHPSlideshow popup code -->
//<script>
//  function pop(){
//      // change this to point to your PHPSlideshow URL
//    var your_slideshow_url="phpslideshow.php?directory=."
//    // change the width and height of your window here to fit your images.
//    winpops=window.open(your_slideshow_url,'','width=640,height=400,')
//  }
//</script>
//<a href="javascript:pop()">My cool PHPSlideshow</a>
// <!--end PHPSlideshow popup code-->
//
// 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!

The part in the script I don't understand are these lines:


PHP Code:
// grab the variables we want set for newer php version compatability
// the @ supress the error messages if your php.ini error level is too high
@$currentPic = $GLOBALS['HTTP_GET_VARS']['currentPic'];
@$directory = $GLOBALS['HTTP_GET_VARS']['directory'];

I don't seem to have the $directory variable until that point.

But anyhow, it works if I open it in a seperate window, you can check it out online:

http://www.ritaandtherocknrollers.com/dev/images/phpslideshow.php?directory=cottage

This doesn't:
http://www.ritaandtherocknrollers.com/dev/html/pics.php?directory=cottage

pics.php uses the following include code:
