Not sure I'd call them instructions, but it's a good overview about what geotagging is.
Not sure about other photo services, but Flickr (the one I use) allows you to manually geotag photos. You can drag them onto a map screen to show their location. It works well if you didn't have your GPS along for the ride and you don't know exactly where the pics were taken, but you know where the trailhead is. Or if, due to privacy concerns, you want to show the general vicinity where the photo was taken.
I might look into the utility you mention in your writeup, since I took some pictures last weekend on a short hike, and I want to place the photos along the hike. I'm not exactly sure how I will go about displaying that on my website just yet. Maybe convert my GPS track with photo waypoints into a .kml that has references to the actual locations of the pictures on my server.
