how to find photos not on memory card

Solution
Try checking the folder you have them moved to, via a computer (connect the phone via USB cord) and see if you can see them on the folder they are supposed to be in on the SD card. If you can see them from the computer, then it is the file manager that is giving you issues. Try restarting the device, and if that doesn't resolve it, try clearing out the cache of the app. If you are worried about file lose, then save the files to a computer prior to ding this, that way you have backups.
