PhotoGPSEditor is easy to use!
The program can be used in one of two mode... either 'Advanced' mode, or 'Wizard' mode.
The easiest way to get to know the program, and to understand how to use it is to use it in 'Wizard' mode as this will walk you through the process. On the application disk image there is a folder (Pict) containing 10 photo files (with_data_1.jpg - with_data_5.jpg, and without_data_1.jpg - without_data_5.jpg). Five of the files are already 'geotagged' and have description/summary meta-data, and five are not. The folder 'gps' contains a GPS data file in the gpx format (it only contains five GPS data points). If the photos are loaded in to the program then the photos with data can be viewed and their location seen on the map, the five matching photos (without location data) can then have data assigned by using one of the methods available in the 'Wizard'.
It should be noted that the photo time-stamp is 1 hour behind the time-stamp of the GPS data (this this the offset), so you should have an offset set to '+1" hour.
