I am having the same problem. Until recently all pictures I saved appeared in the photo library. However, now some appear and some don't appear in the photo library. Of the ones that don't appear in the photo library there is sometimes a picture frame with the word JPEG underneath and sometimes no picture frame at all. Do you already have a solution to the problem? Or maybe anybody else? I do have a lot of pictures stored on my iPad (6000+), however there is still plenty of space available.
