This is a page that can be used to display images in a folder as a slide show. It is a complete html page and should work with minor changes, as long as images meet simple criteria.
Newbie here so be gentle when you bend me over for the rape session. Or not.

<?php
// slideshow.php
// This program will show pictures in a folder as a slide show. The pictures need to be
// similarly named with a number which distinguishes each picture. For instance for the
// example, I have chosen JPEGs in a folder called images, named pic001.JPG, pic002.JPG,
// etc. You can pause the slide show, jump ahead or jump back within the slide show and
// and set the delay of how long a picture stays up after it is loaded.
// Get the variables from the url(QUERY_STRING), and move into hash table $vars.
parse_str($_SERVER['QUERY_STRING'],$vars);
// Get value of picture, time and savetime from hash table and move into $ variables.
$picture = $vars['picture'];
$time = $vars['time'];
$savetime = $vars['savetime'];
// Build the image name including path. In this example go up one folder above where
// slideshow.php is and go into a folder called images. The sprintf(... tells says to
// display the number as a three digit number and pad with leading zeros, 1 = 001.
// Hint, you could change ../images/ to a variable, put variable in url, get var from hash
// table and access any folder on your site (and beyond).
$picfile = "../images/pic" . sprintf("%03d",$picture) . ".JPG";
// Increment $picture before you build next url so you go to the next picture.
$picture += 1;
$url = 'http://www.hitz.info/Haiti04Jun/slideshow/slideshow.php?picture=' . $picture . '&time=' . $time;
// Decrement $picture so you pause on same picture and include save time in $urlpause to
// fill the time input box as the default for restart.
$picture -= 1;
$urlpause = 'http://www.hitz.info/Haiti04Jun/slideshow/slideshow.php?picture=' . $picture . '&time=6000&savetime=' . $time;
// Meta refresh redirect to new page in this case same page with new vars in CONTENT seconds.
// Change if statement to be number of pictures in folder.
// Hint create an image that says end of slideshow or some such as closure.
