ImageMagick Image Upload Thumbnail

Snippet Code

Using ImageMagick, you can easily create image thumbnails faster and much easier than using just php.


<?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{

?>

    <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">

        <p><input type="file" name="photo" /></p>

        <p><input type="submit" value="Upload!" name="submit" /></p>

    </form>

<?php

    foreach(glob($smalDir.'*') as $img){

        echo ' <img src="'.str_replace($_SERVER['DOCUMENT_ROOT'], '',$img).'" /> ';

    }

}

?>
