IPhoto freezes when I try to import photos - why?

Question

Whenever I try to import photos from my camera (an olympus 780) iPhoto takes a long time to 'think about it' and then just freezes. It's the same when I try to bluetooth photos from my phone to iPhoto. Now when I just try to open iPhoto it freezes - why is this? I'm using Snow Leopard 10.6.8 and have iPhoto '11.

Answer 1

First try this: iPhoto_Pref_and_Cache  make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
     User/Home()/Library/Caches/com.apple.iPhoto folder.

3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
