Probably lots of you know this already...I used to do it manually and it took a long time

If you take pictures and carry a GPS with you, you can 'geotag' your pictures.

1) synchronize the camera clock to the GPS clock (you may need to set the camera to UTC time)
2) Have GPS on & receiving; take pictures
3) Back-up your pictures, save the GPS track file as a GPX file
4) Using Microsoft Pro Phototools (free download here http://www.microsoft.com/prophoto/downloads/tools.aspx ) match the pictures to the location. The time the picture is taken is matched to the track point with the closest time; this is assumed to be the point corresponding to the location the picture was taken

5) Save the pictures with the Lat/Long embedded (this is why you work with a back-up file- just in case the program damages the pictures)

6) Upload to Flickr or whatever sharing site you use. Flickr recognizes the geotag in the picture so you can easily link it to a google map

My results are here:

That's pretty cool.

I have a Garmin 496 and a Lowrance Airmap 500. I'm betting the 496 can save to a GPX file, but I wonder if the Airmap 500 can.
 
I'll have to explore that. The Airmap 500 manual says it can save GPS Data files, although I've never done it. According to the manual, it will save up to 9,999 points before it starts to write over the first one. I have no idea what format it is, but I'm going to try it out tomorrow.

I like the idea of using the Airmap 500 because I don't always fly with the 496, but I always keep my Airmap 500 in my flight bag as a backup nav source.
 
Some of the new cameras have a built in GPS chip and will do this automagically, too! Even easier!
