If you recently visited Pinterest you might have noticed some popup messages saying now you can add images to map.
According to pinterest people created more and more boards for uploading and sharing their vacation's photos with everyone. Because of this Pinterest introduced adding images to map feature.
You can make new board and switch “Add a map” option to yes or edit some old board if you want to show photos from that on map. You can add map to every board you want by just editing it.
If you are planning some picnic you should get your camera with you to show people which place is worth visiting.
You are allowed to put different photos on map on different spots. I meant to say, you can add different location to every photo you have in board with “Add a map” option enabled.
