Program for dupes?

Hi guys. What program do you use to fish and kill picture duplicates in your archives? Which would be considered the best for the job? Thanks.

Write a script to name them like their MD5, or a script to identify them and delete them.

If you mean similar looking pics and not exact files though, like the same picture in different formats, different resolution, different scan, scratch, colour vs monochrome, etc., then DupDetector is for you. A great piece of software.
