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 ();
