But like I said: Try Graphic Converter. If you're comparing exactly identical images then the comparison by content is pretty fast, even on my lowly 500 MHz G3 iBook. It probably uses hash tables or something of the kind. Even when looking for "similar pictures" I'm still impressed how well and fast it works.
