How to add GPS position to images

Sometimes it can be very handy to add GPS position to images, so they can be shown on a map. GPS positions can be added to any image (not limited to digital photos). I use Picasa3 to do this job. 

Open a picture in Picasa3 and click the map symbol

Select a position on the world map

 

 

Drag and drop the marker on the right position

 

That's it. Now the image contains a nice GPS position and can be plotted on a map!
