I uploaded 500 pics and now only 100 show.

Question

I transferred 500 photos to Lenovo photo master and after logging back in a couple days later only 100 photos are showing.

Answer 1

I suggest to find the solution at Lenovo forums, there are several users with same or similar problems.

So either 400 photos disappeared which doesn't happen much. If they were stolen they would have copied them.  So either they violated some policy and photo master didn't accept 400 photos with wouldn't happen. Therefore you have either stopped the downloads by leaving and something has needed your permission or something. So it'll be your fault unless you can't find 400 photos in your folders or photo master then that's mystery
