Google Photos Add a Location on Multiple Files I am using Google Photos for my archieved photos. I have lots of photos from past(When the Photo Location not involved)
Now i want to add the location for my Photos to organize them. 
It is possible for 1 image. But there thousands of them. Is there possible way to do it Folder by Folder or Multiple Photos Selection and Add Location to them?
This can only be done through desktop on Picasa web albums as far as I know, but Picasa shares photos with Google Photos, so it should work.


Put all your photos with the same location in an album (you can do this with Google Photos)
Go to Picasa Web Albums and find the album.
Under "Actions", click "Album map"





This will bring you to the album map. Once there, click "Edit map"





Click the first picture in the album to select it, then while holding shift click the last picture in the album.





Drag the pictures out onto the map. You may want to find your location first.
