Duplifinder finds duplicate photos and videos in your iPhoto Library. It can add the duplicates to an album in iPhoto, or move the duplicates directly to the iPhoto Trash.

Note: Duplifinder finds exact duplicates and, in the case of JPEGs, photos which have duplicate image data even if the "metadata" are different. Duplifinder will not identify as duplicates images which have been resized or modified in other ways.

Did not work on my Lion system with iPhoto 9.3.2. Left many duplicates (never edited and with the exact same name) while it made thousands of duplicates disappear forever. The developer claims this is impossible, that I should see them in the trash but I definitely do not. Photos deleted with the manual option are in the Trash, but all the others I pressed the automatic button on are gone. Now I have to figure out whether I've lost last copies, through careful comparison with my backup on another computer. I've erred twice in trying this app but won't again.

I'm sorry you had trouble with it.
Duplifinder matches photos according to their contents, not their filenames or sizes, so photos that have been resized or retouched won't match as duplicates.

Also, Duplifinder only interacts with iPhoto 2 ways:
1. It reads the "AlbumData.xml" file to get the list of photos in the library.
2. When you tell Duplifinder to move photo(s) to the iPhoto trash, it tells iPhoto to do this via Applescript. The Applescript looks like this:

tell application "iPhoto"
remove photo id
end tell

When iPhoto gets that command, it moves the photo from its "Library" to its Trash. In my testing, this moves the photos to the trash, so I don't understand why iPhoto permanently deleted your photos. Perhaps it's a bug in iPhoto.

Does this only checks file names or does it also checks the content for similar images?

Duplifinder calculates a SHA-1 hash for every photo in the library, and then compares SHA-1 hashes.

In other words, it compares the contents of the photos/videos. Photos that have been resized or retouched won't match as duplicates.
