Not on images. What if one image has extra metadata added to it but is otherwise exactly the same as another? What if you have two copies of the same image and one is in TIFF format and the other in JPEG? What if one is a slight modification of the other, say a contrast adjustment for better viewing? Or, say, detect that they are the same image but that the JPEG has been created from the original TIFF and thus is the lower quality image due to lossy compression and therefore keep the TIFF. I would want a photo de-duplicator to be able to detect and report such situations. Cheers Michael.
