Key Imagefield

This module installs a new field type called key_imagefield_image that is a reference field that must refer to a multi-value imagefield on the same entity. it was inspired and partially draws from the Field Reference module. The module allows you to choose a single image out of a multi-value imagefield that can act as a representative image for that entity, and stores the delta. Additionally, the module allows this selection to be overridden by a file-upload. The purpose of the module is to choose a representative image that can act as the "Key" or "Cover" photo in, say, an image gallery or search results.
