      Hello, i want to get camera option when selecting image option in observation form while using it from desktop. While doing R & D we find that bahmni mobile app has that functionality and we want implement same on desktop. 
      When you see observation form on the mobile app there is upload button , when you select it , it has automatic function to select mobile camera or gallery to upload image. We want to implement same on desktop level.
