iPhoto does not have a way to look for duplicates within the application, as it is designed to read the meta data attached to the images, not recognize image similarities
Because of this, you need to do it manually, by selecting an image, (or holding down command and clicking multiple images), then go to "photos" in the top menu bar, and select "move to trash"
If you have too many to do it manually, they look into a software designed to do this, like
1. Gemini: The duplicate finder - https://itunes.apple.com/us/app/gemini-the-duplicate-finder/id463541543?mt=12.
- support phone no. - 1 877 562 2729. Works for more than just iPhoto (can look for duplicates files as well).
2. Duplicate Annihilator - http://duplicate-annihilator.en.softonic.com/mac. and http://www.maclife.com/article/howtos/how_get_rid_duplicates_iphoto.
3. Decloner - http://www.pixelespressoapps.com/decloner/.

1 - what vesion do you have? This feature requires 4 or later
2 - have you looked at their support page - iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ -
Find duplicate photos
It can be easy to have multiple copies of the same photo creep into your iPhoto libraries. iPhoto Library Manager lets you search for duplicates in one or more libraries, view them side by side, and take actions on them, such as moving duplicates to the trash, tagging them with keywords, and more.

It's the new version. It not only has duplicate detection and removal but allows you to browser your library without opening iPhoto. A great upgrade. The dup removal requires a license, however.
