I have a friend who managed to lose some photos a while back, but they "appear" in his iPhoto library. The thumbnails are there but the photos aren't. The photos seem long gone, but the thumbnails seem fairly large- large enough to maybe be useful for some of them. Is it possible to retrieve the thumbnails?
As a side note you can (~/Pictures/iPhoto Library; cmd-click iPhoto Library > Show Package Contents) check to see if they actually still exist. There should be a folder titled "Originals" and "Modified" in there.
Each folder should have subs for years, etc. Obviously Originals are the photos minus any edits while Modified would be the versions of edits (not certain if all versions of edits or only final edit).
Hope this helps.
According to this website, the thumbnails are stored inside
The first location to check is inside of the Thumbnails folder, as mentioned by OP below.
The second place to look would be in Thumb64Segment.data, or ThumbJPGSegment.data. Therefore, I would back up these files and see if there are any applications which can read this file format. I haven't been able to find one after a brief search on the Internet, but I'll update this answer if I do.
A third option might be that this may be happening because of a corrupt iPhoto Library. There's a tool called iPhoto Library Manager, which has a feature called First Aid that let's you:
I haven't tried the software, so I don't know if it will work in your case, but they do have a trial version available.
If you can still view them in iPhoto you should be able to export them. Just select the thumbnail and click file => export.
