If you've got photos with GPS coordinates embedded in their Exif tags, this iPhoto plugin will create a KMZ file so you can view the photos in Google Earth. The file contains everything so you can send it to others and they'll be able to see not only what you saw, but *where* you saw it.
It's free and will remain so, but if you'd like to help me fun an expedition across Japan, check out http://onemanwalking.com
