ImageMagick® is a software suite to create, edit, and compose bitmap images.. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF.

Imagick makes image manipulation in PHP extremely easy through an OO interface. Here is a quick example on how to make a thumbnail:
Example#1 Creating a thumbnail in Imagick
<?php
header('Content-type: image/jpeg');
$image = new Imagick('image.jpg');
// If 0 is provided as a width or height parameter,
// aspect ratio is maintained
$image->thumbnailImage(100, 0);
echo $image;
?>
Using SPL and other OO features supported in Imagick, it can be simple to resize all files in a directory (useful for batch resizing large digital camera images to be web viewable). Here we use resize, as we might want to retain certain meta-data:
Example#2 Make a thumbnail of all JPG files in a directory
<?php
$images = new Imagick(glob('images/*.JPG'));
foreach($images as $image) {
// Providing 0 forces thumbnailImage to maintain aspect ratio
$image->thumbnailImage(1024,0);
}
$images->writeImages();
?>
