Do the photo times fall within the time frame of the track log?
In order to geocode a photo, its timestamp must fall between the time of two consecutive track points in a given track log segment. Photos taken outside the time span covered by the track log can thus not be geocoded. If you expect the photo to fall within the correct time frame, you may want to double check the camera time zone and clock error settings. Remedy: Either anually enter coordinates or geocode manually using Google Maps or Google Earth.
