Question

How do I get photos from the iPhoto import folder to the iPhoto library?  It uploaded, but hung while deleting from my camera, so no imported photos are in the iPhoto library.  I watched it upload about 400 photos, one by one.  They're somewhere, but they don't appear in the iPhoto library. As iPhoto was deleting them from my camera, it got hung up, then a message came "you should eject before disconnecting a device."  I hadn't touched the camera.  The message came by itself.  I couldn't get iPhoto to respond, so I disconnected the camera and did a Force Quit.  Opening it back up, the pictures were gone.  Can somebody help me? 

Answer 1

What version of iPhoto are you running?  Assuming it's iPhoto 9 or later Apply the two fixes below in order as needed:
Fix #1
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
2 - run Option #4 to rebuild the database.
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 and select the library you want to add in the selection window..
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ 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 but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
