phMagick is wrapper for ImageMagick written in php 5, and it’s designed with to ease the developer job by wraping ImageMagick complexity in easy to use functions.
It allows you dynamically generate thumbnails and catching effects like drop shadows, watermark images, write text as an image, create a mirror or reflex effect to images all without opening photoshop just with Php and ImageMagick. The main reason for making phMagick is to avoid the inefficiency of GD and php memory limits
