iPhoto '09 - Thumbnails visible but no photos! (exclamation mark)
I'm in a bit of pickle here and I hope someone can help me. I take photos pretty regularly. Nothing mind-blowing, but I use my iPhone to take pics of my dogs, my girlfriend, etc. I sync my phone pretty much everyday and I just realised today that I'm missing a bunch of photos that span over 4-5 months. The thumbnail for the album itself is BLANK, but when I go into the album all the thumbnails for the photos are still there. However, when I try to maximise the photo I get nothing but a big grey exclamation mark.
I have tried different things like 'Open in Finder' and expanding the iPhoto app to show the folders inside and then try to find the photos myself, but nothing seems to work. I have also tried rebuilding my library with no success. I checked my recent Time Machine save, but somehow the iPhoto backup shows the same events in my iPhoto having issues. I don't understand how this could have happened, because I upload and sync my iPhone so often that I should've noticed at one point over the last month that my photos were missing - I have trouble believing I could've missed these missing events over the last month every single time I synced. But my last save shows the same thing and I don't understand how this is possible. I'm stupid for not having backed up my photo collection another way, but I thought I was being pretty careful.
Is there a bug that can cause this? What else can I do to get my photos back? or am I simply S.O.L.? I have read about many horror stories about iPhoto 09 but nothing that covers my situation closely enough to help me.
Any help would be appreciated. I apologise if I wasn't clear or if I didn't give you enough details.
Thanks in advance for any help!
