slideshow: glob issue?

[jace41]

Got this slideshow script from a third party and made some modifcations to work with php 4.3. No php error has came up, but no "slideshow" images have come up. I'm still new to php stuff and I gather that the problem may lies with the glob function since it seems not sending the image paths to other functions to process the slideshow. Am I right?

<?php

// open the folder and locate the files end with .jpg
$dh = glob( "blah/blah" );

$files = array();
foreach( $dh as $file )
{
  if ( preg_match( "/[.]jpg$/", $file ) ) $files []= "$file";
}
?>

In case the glob function is right, other functions below:

<script>
// list images
var image_list = [
<?php $first = true; foreach( $files as $image ) { ?>
<?php echo( $first ? "" : ", " ); ?>"<?php echo( $image ); ?>"
<?php $first = false; } ?>
];

var curimage = 0;

// grab and resize image
function switchimg( ind )
{
  var image = image_list[ind];
  var obj = document.getElementById( "selimg" );
  obj.src = "scale.php?image="+image+"&y=230";
  curimage = ind;
}

// next image
function nextimage()
{
  curimage++;
  if ( curimage >= image_list.length ) curimage = 0;
  switchimg( curimage );
}

// timer
window.setInterval( "nextimage()", 3000 );
</script>

html output:

<img id="selimg" height="230" src="scale.php?image=<?php echo($files[0]); ?>&y=230" />

scale.php:

// get current image and resize
<?php
$image = $_GET["image"];
$maxy = $_GET["y"];

$im = @imagecreatefromjpeg( "blah/blah/".$image );
$curx = imagesx( $im );
$cury = imagesy( $im );
$ratio = $maxy / $cury;
$newx = $curx * $ratio;
$newy = $cury * $ratio;

$oim = imagecreatetruecolor( $newx, $newy );
imageantialias( $oim, true );
imagecopyresized( $oim, $im, 0, 0, 0, 0,
	$newx, $newy, $curx, $cury );

header( "content-type: image/jpeg" );
imagejpeg( $oim );
?>

In scale.php:

// get current image and resize

^^that needs to be inside the PHP tags otherwise it causes output and you get a 'Cannot modify header information' error.
