It's not a total disaster - I still have the photos on my device. But whilst I was adding a video to an album, it froze up, and then removed 1500 photos I had previously added (it kept the 300 photos my partner had added). So unless I can find a way to restore the album, I'm going to have to spend hours sorting through 6 months (thousands) of new baby photos. Please tell me there is a way!
