Geotagalog lets you open a tracklog and then pick a source of photos. The photo positions can be fine-tuned along the tracklog using time adjustments. The photos may be previewed in place before import into the current iPhoto library.

Geotagalog does not currently tag photos once they are imported into your iPhoto library. For the best workflow, set Geotagalog to launch when you connect a camera, and let Geotagalog import your photos into iPhoto for you.
