1- stay out of the iPhoto library. It is a SQL database and there are no user serviceable parts in it and any changes to its structure or content will corrupt your library and cause data loss
2- have you emptied the iPhoto trash (iPhoto menu ==> empty trash)?
3- depending on the version of iPhoto you have (you failed to mention it) the data folder has the small previews of your photos, modifies folder the edited versions and the originals folder the original versions
I have not emptied the trash. I have version 6.0.6.
I have a problem with my iPhoto. Some of my pictures can be viewed as thumbnails, but if I click on them to enlarge them, I get a grey box with "!" in the middle. These few pictures can't be copied to the desktop, and they can't be synced to my iPad or iPhone.
This all happened after I had to restore my hard drive (from Timeline) onto a new hard drive on the same computer.
Any ideas from anybody?
The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Try these in order - from best option on down...
1. Do you have an up-to-date back up? If so, try copy the library6.iphoto file from the back up to the iPhoto Library allowing it to overwrite the damaged file.
2. Download <a href="http://www.fatcatsoftware.com/iplm/"><b><u>iPhoto Library Manager</b></u></a> and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
3. If neither of these work then you'll need to create and populate a new library.
To create and populate a new *iPhoto 6* library:
Note this will give you a working library with the same Rolls and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library on your desktop and find the Originals folder. From the Originals folder drag the individual Roll Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.
