After opening a tracklog, choose a source of photos to geotag using the "Choose photo source..." pull-down button below the map.

Geotagalog can geotag photos directly from an attached camera or card reader. Make sure your device is connected, then pick it in the "Choose photo-source..." pull-down menu. Using this workflow is the easiest way to GPS-enable your camera.

Geotagalog can also geotag all photos in a folder. Click "Choose photo source..." and then pick "Choose folder..." in the pull-down menu. Geotagalog will load all supported photos in the folder you open and all its subfolders.
