When a survey answer has a picture attached, the picture is saved in own mobile folder "/storage/emulated/0/Android/data/com.ifsworld.mworkorder.apps10/files/Pictures/WO/T5941581/Pictures/N8.jpg".

The user can uses the mobile offline or online(with this option, some failed transactions can exist), for both options, the pictures are not upload to database, because sync still not happenned.

So, if the pcitures were not upload and the user do a logoff and logon in the app, the folder "/storage/emulated/0/Android/data/com.ifsworld.mworkorder.apps10/files/Pictures/WO/T5941581" is deleted.

And now, there is a reference in the MOBILE_WORK_ORDER_PICTURE_TAB, but the picture was deleted from mobile.
