iPhoto exploded several times during our importation of a stock 25,000 mixed JPG and MOV image set. The iPhoto app also imports images from sources in a way that creates events that aren’t easily labeled. Merging multiple large events together also crashed iPhoto. We repeated the crash on two different machines, a Macbook Air and a Macbook Pro, although this sample size is very small and might be considered anecdotal. In all of the explosions, however, iPhoto seemed to know that it had caused a problem, and knew where to pick up from where it crashed. iPhoto’s job of handling duplicate image import, however, doesn’t work well, and we were easily able to import thousands of dupes.
