Above image show you it was a Google Map. I use my DX900 Acer phone which has GPS send the location through my server and then keep a location to generate the map by showing the markers and path. One of my friend is also crazy working on it just like I did. Haha.
This is an idea to apply for anything with GPS, FaceBook, Map. I just use static map so it does not load a memory of computer or phone browser. Also then you can post your location to your facebook wall and friend’s home live feed by clicking on the map.
It show the thumbnail map and the location of the latest spot you were at!!
So the programming on FaceBook is not difficult at all, but you need to learn their tags and API.
