Photo's not displaying after upgrade

Question

It appears that iPhoto is recognizing my photos as it tells me how many I have (and how many events), but the thumbnails don't show (just a place holder). If I double click on a thumbnail place holder, I get a large pixelated exclamation point.
When I start iPhoto, I get the message "rebuilding thumbnail caches" and a status bar which quickly ends.
My library is where it was with iPhoto 6...in the shared folder with a link to it from the pictures folder.
any ideas? thanks

Roger:
Since rebuilding didn't resurrect the library you may be looking at starting over with a fresh library and importing the original photos from the old library like this:
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.
