Lost photos while editing in iphoto

Question

I was editing an album on iPhoto (while not connected to Internet, dont know if that matters) when iphoto crashed. When I reopened iphoto only the first (of many imports) import's photos were showing. I don't really want to reedit all those lost photos but when I plug my camera in it says that all photos were already imported and even shows the little previously edited thumbnail as an option to replace if i try to reimport (which I cancelled since those edits must be somewhere then) But why can't I view them anywhere in the library??

Answer 1

Apply the two fixes below in order as needed: 
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with
Option #3, followed by #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager  to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next  window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments.  However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
