This is what I looking for so long time! – Slidebox - Photo Manager Review

I can organize my photo album much effectively thanks for this app. But I have one question. I can't see some photos on this app even though they are in my photo album. I can't see them anywhere on this application-unsorted, timeline, and album. So I'm having trouble to sort my photos. I would greatly appreciate if you let me know how to solve this problem. Have a nice day.
