I have been taking photos of my family for almost a decade, but I have been to lazy to take care of them. So I'd just copy them to hard drives to back up, and forget them. Every dozen or so months I would copy photos from others, or copy photos to a computer, or to another hard drive, with the intention to organize them. I copied all the photos to a single hard drive and then imported them to iPhoto thinking that iPhoto would take one of each photo. (yea, go ahead and laugh at me now.) I was wrong. Ten years of finger happiness (I have four kids) and procrastination has resulted in nearly 200K photos and 400 GB. Does anyone have any experience with software that can delete duplicate photos? Anything that anyone would pay for? I think that I probably only have about 10k real photos and the rest are unorganized duplicates. It can be for Mac or PC because I use both. I just want to click a button and come back several hours later and be done with it. Thanks!
