You're right. File systems' directories do not store the file names in any sorted order. I'm sure there's an explanation for how they do store them, but it doesn't matter. If you want to deal with files in a sorted manner (by file name, last modification date, creation date, or whatever), you need to do the sorting on your own. This generally means reading all of the file names into an array and then sorting that array as needed, as in something like:

<?php
$directory = 'images/slideshow';
try {
// Styling for images
echo "<div id=\"main\">";
$slidefiles = new DirectoryIterator($directory);
asort($slidefiles);
foreach ($slidefiles as $item ) {
if ($item->isFile()) {
$path = $directory . "/" . $item;
echo "<img src=\"" . $path . "\" />";
}
}
echo "</div>";
}
?>
