Is there a way to make a few images with Image Crop out of one uploaded file? Currently i have to upload the same, big pic to get new pics with various dimensions. Unfortunately the "Imagefield sources"-module doesn´t support Image Crop. Is there an alternative?
I don't understand your requirement very well. But if you want multiple versions of the same image it sounds like a use-case for imagcache ( http://drupal.org/project/imagecache )
