On flickr some photos have a little map that shows where the picture was taken?

Does the Nikon D3100 have the ability to do this?

That has nothing to do with your camera is is a Flickr function.,., Just click on your picture and look over to the right. It should say Add this photo to your map.click there then type in your zip code.click on the marker and move to where you took the picture then click Save.

Agree with above answer, Though some cameras have a GPS function that can help with accurate plotting. The D3100 hasn't got this.
