    i had a couple of that also... i just clicked OK cos it says it would optiimize performance... but i think it has something to do with the fact that iPhoto organizes photo files into folders containing originals and also one for thumbnails. I think mine rebuilt its thumbnail cache 4x already for the past 4 months.

    iPhoto is telling you that the thumbnail database is a bit messed up and needs to be rebuilt for optimum performance. Go ahead and click OK. It doesn't affect your actual pics.

    Backup first before you clich k that OK button that rebuilds your thumbnail cache
    I had a bad experience (thrice) and all my thumbnails were gone.
    I had to reimport the photos everything again.
    Now im using Aperture as my default photo management organizer.
    No more worries

    Taken from the Apple website quoted above - iPhoto 4 or later: Rebuilding the iPhoto Library

    Warning:
    Because some data or photos may not be recovered during the rebuild, you should back up your existing iPhoto Library folder, which is located in your Pictures folder, before using the rebuild feature.

    Aperture has a much better function and other adjustment features not found in iPhoto. It doesn't eat up your hard disk space as fast when you make adjustments unlike iPhoto. You add another photo (same size or even bigger) to the library with the original one while Aperture only copies the instructions as file and not another photo file.

    Why don't you check out what's Apple Aperture and judge for yourself.
    I never looked backed after using Aperture 1.5

    At least you haven't lost any photos yet. Better do a regular backup of you photos.

    You just see a grey box is a question mark.

    oh boy! and goood thing i asked first before i did anything :D

    i just like to keep things simple by not installing another app in my mac, have too many of those things already. i think :D besides, iphoto came with the mac so i might as well use it. i think i am better of editting pictures in adobe when i want to do some hard core editting.

    thanks guys :D

    Yah, no need to spend extra on Aperture if you don't really need it. I haven't had any problems with iPhoto rebuilding my thumbnails, but to be on the safe side, as others have suggested, just make sure you have a current backup of your iPhoto Library folder before you proceed.

    You should be backing up anyway, at least your Users folder.

    I have yet to encounter any problems resulting from a rebuilding of the thumbnails. All of my clients and students use iPhoto, some extensively (even professionally) and others casually. I have yet to see one come across the problem reported by renzo.

    Of course, as Patrick stated, it's only prudent to backup your beloved data. However, I wouldn't be too worried of the rebuild the thumbnails. You might even have better chances of winning the lotto compared to losing all your pics because of the utility.

    Even if the problem Renzo reported happens to you, there's a way to recover the lost thumbnails. Just hold the Command (Apple) and Option keys while launching iPhoto. You'll get the Rebuild Photo Library dialogue box. From there, check the first two options. That will restore the blank thumbnails.

    Question on Aperture though is... does it incorporate itself with other Mac applications? like the MEDIA section of iWorks, iDVD, iMovie, etc?

    I backup mostly because I'm afraid of a hard disk crash, not because I'm afraid of a software malfunction.

    Last year, I've had to restore both my own PowerBook and my wife's MacBook system because of hard disk failures. I killed 2 other hard disks in external enclosures, plus the hard disk in my 4G iPod. All the times I've had to restore my data, it was because of a hardware problem or a user mistake, not because an application caused the data loss.

    Bottom line, hard disks WILL fail, and a CURRENT backup (do it at least weekly) will mean the difference between a minor inconvenience and utter despair.

    Hold down the Command and Option keys when launching iPhoto when you want the rebuild options to come out.
