to crop (and scale) an image after uploading.

Configuration and Usage
After installing the module you need to configure your image styles before you
can start cropping. Go to
Administration » Configuration » Media » Image styles
and click on the "edit" link for the styles that need a Manual Crop effect.
Add and configure one of the Manual Crop effects. You'll notice that the Manual
Crop effect will always become the first effect in the list. This is because
cropping should always be done first, otherwise the result will be unpredictable.
Next go to
Administration » Structure » Content types and click on the
link (the Field UI module should be activated) for the content type that should
allow cropping. Now click on the
edit link of the image field, so you can enable
and configure Manual Crop (open the "Manual Crop" fieldset) for the current field.
After saving the settings you should return to the content type overview and click
manage display so you can set the (cropped) image style that should be used.
Manual Crop adds a "?c=md5_hash" query string parameter to the image url so the
at client-side cached image gets refreshed whenever the crop selection changes.
To prevent an SEO impact, this can be disabled by unchecking the
Reload cache-control setting at
