How To Use New Facebook Photo Reply Comment Feature

Suddenly when I was browsing through of my facebook update, I noticed the new option of adding a photo in reply over the facebook status update.

I could see a new camera icon while replying to a person as you can see in the image below.

Once I clicked over the icon it allowed me to upload a photo in reply


Once I selected the photo, I could see it getting uploaded and once uploaded it the was there in the reply comment and it also allowed me to add a comment while uploading a photo.
