simple question about image crop

[outermotion]

hey guys, not a programmer, have a simple project i am trying to implement

 

i have it working sort of,...

 

any help would be greatly appreciated

 

i am trying to crop all images in a folder and display them, but i keep getting line breaks in my images.

 

i know its silly but i am just trying to learn a little something through this.

 

crop.php

<?php
$w=$_GET['w'];
$h=isset($_GET['h'])?$_GET['h']:$w;
$x=isset($_GET['x'])?$_GET['x']:0;
$y=isset($_GET['y'])?$_GET['y']:0;
$filename=$_GET['src'];
header('Content-type: image/jpg');
header('Content-Disposition: attachment; filename='.$src);
$image = imagecreatefromjpeg($filename); 
$crop = imagecreatetruecolor($w,$h);
imagecopy ( $crop, $image, 0, 0, $x, $y, $w, $h );
imagejpeg($crop);
?>

 

index.php

[HIGHLIGHT="PHP"]<link href="style.css" rel="stylesheet" type="text/css" />
<h1>2 pixels. every 5 minutes . dojo desktop workflow experiment</h1>
<div id= "wrapper">
<?php

$images = "./"; # Location of small versions
$cols   = 1; # Number of columns to display
$thecode = "crop.php?x=0&y=200&w=1600&h=2&src=";
if ($handle = opendir($images)) {
   while (false !== ($file = readdir($handle))) {
       if ($file != "." && $file != ".." ) {
           $files[] = $file;
       }
   }
   closedir($handle);
}

$colCtr = 0;

foreach($files as $file)
{
  if($colCtr %$cols == 0)
  echo '<img src="' . $images . $thecode . $file . '" />';
}

?>

</div>

current output is here, you see the problem there. http://dojo.outermotion.com/workflow
