Upload images and generate thumbnails using ImageMagick

Using ImageMagick you can create thumbnails easily and faster, much easier than with PHP.

 // Location to upload main image:
$mainDir = $_SERVER['DOCUMENT_ROOT'].'/images/l/';
// Location to create the thumb image:
$smalDir = $_SERVER['DOCUMENT_ROOT'].'/images/s/';
// Command to use:
$command = '/usr/bin/convert';
// Thumbnail width:
$size = 210;
 // Make sure we have an image:
if(isset($_POST['submit'])){
 if(getimagesize($_FILES['photo']['tmp_name'])){
 $name = $_FILES ['photo']['name'];
 $uploadfile = $mainDir . $name;
 move_uploaded_file($_FILES['photo']['tmp_name'], $uploadfile);
 $lrgImg = $mainDir . $name ;
 $smlImg = $smalDir . $name;
 $imageMagick = $command . " '". $lrgImg . "' -resize '$size' '" . $smlImg . "'";
 shell_exec($imageMagick);
 }
 header("Location: /test.php");
 exit;
}else{
?>




 foreach(glob($smalDir.'*') as $img ){
 echo '  ';
 }
}
?>
