[magick-users] slice up an image

[Fred Weinhaus]

I believe that -crop should do it automatically (if your image is 
evenly divisible by the subsection sizes)

convert image_480x360.jpg -crop 160x120 images_160x120.jpg

see http://www.imagemagick.org/script/command-line-options.php#crop

also see my example for 2 overlapping halves at 
http://www.fmwconcepts.com/imagemagick/tidbits/image.php#crop
