We got a chance to talk to members of Karnataka Philatelic Society about OpenPostBox. They are very interesting set of people. They have also started sending me the postbox pictures using WhatsApp along with location. Now I need to find an efficient way to extract them and insert into my database.
As of now I am thinking of Export -> Parse -> Insert. Working on it. If you have any ideas do email me.
Details of the meet are on my personal blog if you like to read.
