Approaches for managing a library of digital images and information about any editing operations performed on those digital images are provided. A managed library of digital images and a referenced library of digital images may be maintained. Digital images may be moved from the managed library of digital images to the referenced library of digital images, and vice-versa. A preview digital image data may also be generated from master digital image data. Rather than performing image operations directly on the master digital image data, change data that identifies one or more operations to perform to a digital picture represented by either the preview digital image data or the master digital image data may be stored, thereby allowing operations to be performed on the preview digital image data when the master digital image data is not accessible. Digital image may be automatically renamed based on rules for doing so.
