Manual Control of ImageCache Cropping with Imagecache Javascript Crop Module
While Imagecache is a stellar tool to automatically create and display resized and cropped images on your site, sometimes a bit more control is necessary.
Imagecache cropping is an automatic process that crops from the center of your image. So, if the most interesting part of your image is in the upper-left, it will most likely be cut off at least partially in the resulting image.
