Image resize & crop module for Kohana Framework. This module can be configured to use an image cache to prevent constant image regeneration. It was tested with JPEG and PNG images.
Syntax is: resizer/<type>/<width>/<height>/<file>
Where could be c (crop) or r (resise)
<img src="<?php echo Kohana::$base_url; ?>resizer/c/150/150/images/sample.jpg" />
This would return a 150x150 px cropped JPEG.
