Problem downloading photos from iPhone to iPhoto on MacBook
I can't download photos from my iPhone 5 to iPhoto anymore. It comes up with an error message that says 'The following file could not be imported. (The file is in an unrecognized format.)' My software is up to date. The photos were taken on my iPhone, however there are also some photos that I have saved from other people who sent them as a text message. How can I save my photos please without loosing them? I have tried to save one image only, not all of them, and nothing work. Suggestions appreciated. Thanks.
MacBook Pro, iPhoto '09 V8.1.2
