4. The image processor-implemented method of claim 1 , wherein storing the candidate content-relevant metadata data further comprises automatically storing changed metadata with respect to a plurality of related images.
1. An image processor-implemented method for associating metadata with image files, comprising: automatically identifying a single image file with existing metadata; automatically analyzing the image content of the single image file to determine candidate content-relevant metadata; automatically comparing the candidate content-relevant metadata to the existing metadata of the single image file to determine inconsistency; automatically using the determined inconsistencies to identify that the candidate content-relevant metadata is completely consistent with the existing metadata or inconsistent with the existing metadata or includes data that is both consistent and inconsistent with the existing metadata; when the candidate content-relevant metadata is completely consistent, then storing such candidate content-relevant metadata that is consistent with existing metadata in association with the single image file; when the candidate content-relevant metadata includes an inconsistency, then presenting the single image file and at least a portion of the inconsistent candidate content-relevant metadata to a user; permitting the user to accept the determined at least a portion of the inconsistent candidate content-relevant metadata or the existing metadata; and storing the user accepted metadata in association with the image file.
