Support ImageMagick PHP extension #253

Manual page: https://www.php.net/manual/en/book.imagick.php

ext-imagick are available on most shared hosting (on CPanel, there is a section page for modules). php-imagick on VPS (or Linux in general) is available on package manager or pecl.

I suggest to add lines of code to check if this extension loaded, then use it. If not loaded then do exec(). Something like this:

} else if (extension_loaded('imagick')) {

  // do crazy stuff with Imagick

} else { // ImageMagick

  // convert via exec()
