This is a known issue in the PK4 TimeTracker application.

The photos that are clicked when on offline for the Check-In/Out are not saved.

The current build of PK4 Time Tracker application does not have the ability to save the photos taken when on offline. The PK4 Tech team is working on the app, and the offline photos will be supported in one of the upgraded version of the PK4 TimeTracker application.
