All my pics are safe in their respective folders, but the thumbnails of my earlier pictures have sudenly gone wrong. The wrong thumbnails show up in the main window, but when you click on one it takes you to the right picture in the right album or roll. I have rebuilt the iPhoto library and it did no good. How can the "wrong" thumbnails have got linked to the "right" photos?
Hi petepete3,
Try again this time try it this way.
Close iPhoto
Navigate to your iPhoto Library folder in the Finder.
Drag to the desktop the three loose thumbnail files called Thumb32Segment.data, Thumb64Segment.data, and ThumJPGSegment.data.
Hold down the Command and Option keys while launching iPhoto until you see the rebuild screen.
Choose the first two options to rebuild the thumbnails.
If that doesn't work.
Navigate to your iPhoto Library folder in the Finder.
Drag to the desktop the three loose thumbnail files called Thumb32Segment.data, Thumb64Segment.data, and ThumJPGSegment.data.
Drag the folder called Data to the desktop
Hold down the Command and Option keys while launching iPhoto until you see the rebuild screen.
Choose the first two options to rebuild the thumbnails.

Hi Lori
Thank you, thank you! Your first suggestion did the trick. The rebuild took a long time, but all seems to be OK again now.
The exact thing happened to me: garbled thumbnails. I've been having thumbnail woes ever since I upgraded to iPhoto 6.0 & 6.01.
Today it went from bad to worse. Out of the blue today, thumbnails disappeared and reappeared with the wrong picture....hence the garbled description.
Some history: Since upgrading to iPhoto 6.0, I keep getting warnings to rebuild my thumbnail cache. I crash every single time I try to rebuild my thumbnail cache (either from the initial prompt or from starting up with command option).
I just tried the steps Lori recommended (removing the Data folder & the 3 Thumbxxxx.data files) and then rebuilding the thumbnail cache after launching with command option keys. iPhoto worked on rebuilding the thumbnails for about 2 hours. Then, when the progress bar was 95-98% done, iPhoto crashed (just a like every other times!)
Finally broke down and called Apple Tech Support. The TS guy seemed frustrated by all of my attempts to fix the problem. He kept asking who told me to do that, and I kept replying the iPhoto Apple Discussion board! He told me I have to rebuild my library from scratch (after backing it up).
I'm still hoping to avoid that. So any other tips or hints? Any other files related to thumbnails that could be corrupted? I now have incomplete thumbnails with missing pictures.
I am seriously considering going back to iPhoto 5 (especially since Homepage is gone (Forever????), and my Mom (with her ancient WebTV) can only see my web pages created with HomePage...and creating a web page manually is such a pain! iWeb doesn't seem to work with WebTV and many members of my family use it.
I have pretty much the same problem (using iPhoto 5.0.4 ).
I had just done an archive and install, and all the earlier photos turned into grey square thumbnails. Opening individual pictures gives a big grey square.
I have tried rebuilding libraries, and deleting thumbnail files as described here and in similar posts, but the final option (creating a new library and importing the old photos) is not one I'm keen on.
I believe (but am not sure) that this will result in a loss of all folder, film roll and album allocations, and will import any modified photos in both their original and modified format. This will effectively trash a great deal of work I have done putting all this 'metadata' together.
This is a very common problem looking through forums, with a number of different scenarios leading to the same symptoms. Apple's failure to respond to this is very disappointing, and it seems we are forever offered work arounds (with loss of our own time and in this case metadata) rather than solutions to what is downright flawed programming.
Has anyone found a solution yet that wont kill off days of my hard work structuring my iPhoto library?
