Q: Where are my pictures?

I have just imported 667 pics off my new Nikon to iPhoto.  At the end I agreed to delete the files from my camera. Somehere whilst "finishing import", iPhoto crashed. Now when reopening, I can't see the pics.  Where are they? Not in events, recent import and not on camera.  Ouch.  There seem to be 227 remaining files on the camera, but if I try to import them, it says they already exist, which gives me hope that the others do to... but WHERE are they?  Help me, this is an entire vacation and a birthday!!!
