I'm not sure what happened, but I can no longer import photos from my iphone to my Mac. iPhoto and Lightroom both say there are 26 photos to import on my iPhone. However, when I try to import, it says the files are not valid and fails (screenshot attached). The odd thing is that I actually have 48 pictures on my iPhone under Camera Roll. I have no idea how I can fix this problem. I really want to save the pictures under the iPhone camera roll. Any ideas or help? Thanks!
