Well, I don’t feel alone. I tried to create a Bookify with about 200 images, averaging about 200 kb per image (mostly vintage B&W). Thumbnail images popped up on my monitor and I could see the uploading proceeding image by image. However, the process stopped at about the 30th image. Tried multiple times over two days, but the most I could ever upload was ~60 images. I was prompted to go to BookSmart for faster uploads if I had many images. I did and had no problem finishing a 38 page book with most of my images. I even received the 25% Bookify promo discount. Bookify is not ready for prime time- at least for >60 images.
