So I am pulling years and years worth of pictures and duplicates of pictures from several different hard drives and computers. I know that I have duplicates and possibly worse of images.

A question for those of you that keep on top of your pictures, what software would be the best for de-duplicating and organizing all of these pictures?

I know I can Google this, but I wanted input of actual users.
