CodeIgniter has support for image cropping:

CI supports GD/GD2, NetPBM, and ImageMagick:
http://php.net/manual/en/book.image.php
http://netpbm.sourceforge.net/
http://www.imagemagick.org/

Here are some manual ImageMagick examples:

In PHP, ImageMagick may be executed using the exec function:

exec("convert my_image.jpg -resize 50% -crop 80x80+0+0 my_thumb.jpg", $report);
print_r($report);

PS. The UI is a different story!
