Jpegs 'missing' in edit mode

Question

Since upgrading to iPhoto 08 I have found a couple of problems. This one is the worst;
Some jpegs show when browsing but will not display (their RAW versions will be okay). All of their information is there & their files are in the right place but iPhoto will not open them.
When I attempt to re-import them iPhoto says that it cant import as the file is already in the library.
I have tried all other advised steps revert to original etc & nothing works.
I have dumped the iphoto .plist that didn't work & made a different problem worse.
The files will open with preview so they are not corrupt.

Adam:
It appears that you're going to have to start with a new library and import the Originals folder from the old one because the database file has been damaged. That is unless you have a backup copy of either the Library6.iPhoto dB file or the entire library. If you do try replacing the dB file in the library package with the backup copy (as long as it's fairly recent and no imports have taken place since the backup).
Here's how to start with a new library:
Creating a new library while preserving the rolls from the original.
Move the existing library folder to the desktop.
Open the library package like this.
Launch iPhoto and, when asked, select the option to create a new library.
Drag the Originals folder from the iPhoto Library on the desktop into the open iPhoto window.
This will create a new library with the same Events as the original library if you have the Finder checkbox unchecked in the Events preference pane.

TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
