Changes made to the attachments are not permanent until you save the results, at which time your custom cropped version will overwrite the default file at that preset's location in the Imagecache filesystem.
In your theming you can use the imagecache theme function with your defined preset. The imagecache action will make a database call to choose the right crop area and (if necessary) scale down the image first.
The main difference with projects like eyedrop or imagefield_crop is that it doesn't provide it's own widget to upload images, instead it just 'hooks' into the image-handling modules you are already using.
image and Acidfree Albums : Link is underneath the thumbnail on the edit page.
Node Images : Underneath the thumbnail. You will need to add an override function to your theme's template.php; see README.txt for details.
Everyone is invited to submit patches supporting other modules. Use the issue queue for patches and discussion.
Three screencasts are available:
http://www.screencast.com/users/timmillwood/folders/Jing/media/ef47425b-... : Drupal 6
http://realize.be/imagecrop-5x10-out : first release
http://realize.be/imagecache-2-and-imagecrop : early development
Core Image module should be enabled
If you use jquery update. Make sure you also have the latest version from jquery_ui. (For example jquery update 1.3.2 needs jquery ui 1.7.3, and vice versa)
More info is in the README.txt file.
Imagecrop supports several modal modules to open your popup with.
Supported modules are:
- colorbox (make sure you included node/*/edit in the module settings)
- shadowbox (make sure you included node/*/edit in the module settings)
In the Drupal 7 version, only colorbox and iframe are supported at moment. Other modules will be added, when they are ported
