Iphoto- Can see thumbnail, but when clicked a circle with a gray circle and a black exclamation point shows up.
Once I click a picture in Iphoto this pops up.
I can clearly see the picture when its in a thumbnail. I have really Important pictures of my whole family and I would be so devastated if I lost them. I didn't mess around with Iphoto at all. All I ever did was upload pictures to it and one day this started happening to ALL my pictures on there.
