Create thumbnails on-the-fly using Imagick

OK, this will be simple. I said it’s simple, more simpler than anyone can expect. Let’s see the overcomplicated code:

<?php
$im = new Imagick( 'path/to/your/image.jpg' );
$im->thumbnailImage( 200, null );
header( "Content-Type: image/jpg" );
echo $im;
?>

That was all. Yup.
OK, now step by step:

1. We instruct Imagick to work with the file from the parameter.
2. Ask nicely Imagick to create a thumbnail: width should be 200px and no fixed height. That’s good, cos Imagick will automatically preserve the aspect ratio, so, bye-bye ugly thumbnails
3. Set the correct Content-type header
4. echo() the Imagick object which contains the image data, namely $im

That’s all. We saved the world again…
