all iphoto pictures gone. rebuild not working.
I have iphoto 11. All pictures are gone. In their place, the thumbnails are empty. When we look at the pictures, there is a black triangle with an exclaimation point in the middle of it. I have tried the option+command control with iphoto and tried all the options twice. That had no improvement. I also downloaded iphoto manager to see if that helped and that also made no difference. I am open to any suggestions before I give up and try the apple store or some local repair place. I know that the pictures are still there - when i scroll through the list of blank events, there is a flicker when the actual pictures show up and then goes away again. thanks.
