Imagick Thumbnail From Center

There are exactly 983,292,023,674 thumbnail scripts available on the internet. All do basically the same thing, take an image and resize it to a given size. Here we use a different approach by cutting out the center of the image and using that as a thumbnail. This makes for a more artistic thumbnail however, your mileage may vary if the subject of the image is not central. This may not be such a bad thing as it may pick up some additional aspect of the image, but depending on the image composition, may just pick up a black blob.
