I had to go and buy a backup disc. I've now backed up my photos and tried all the options to repair and rebuild. I got rid of the one photo that showed on all events as the key photo but now no thumbnails show. The squares in events are black. When I open an event all squares are dark. If I open one of these squares I can then see the picture and the bar at the bottom shows all pictures in that event.
In the repair did you try the first option, i.e. repair permissions? The repair of thumbnails sometimes takes 3-4 tries its been reported.
You can run this rebuild:
Using iPhoto Library Manager to Rebuild Your iPhoto Library
- Download iPhoto Library Manager and launch.
- Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
- 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
- In the next window name the new library and select the location you want it to be placed.
- 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.
Note the in struction was not to backup your photos -- it was to backup uyour iPhoto library - two totally different things - the library contains much, much more than just the photos
Back up your iPhoto library,
See TD's post in this thread -- https://discussions.apple.com/thread/3857057?start=0&tstart=0This helped meRe: iphoto imports upright photos as black
There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). (On iPhoto 11 this option is under the File -> Reveal in Finder.) Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help:
As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?
I did try all the options but I did so one at a time. Should I have checked all the boxes at the same time? I will try them all again a few times and if that doesn't work will download iPhoto Library manager.
Before doing this I did back up my computer so I'm assuming that iPhoto Library is properly backed up (I'm obviously fairly new to all this).
Thanks for your help so far.
