Why would someone choose to integrate a picture or photograph into a text?

Vision trumps all senses. Pictures beat text as well, in part because reading is so inefficient for us. Our brain sees words as lots of tiny pictures, and we have to identify certain features in the letters to be able to read them.

yeah we often use picture like Gif or any sticker or any of our pictures because we use them to make the conversation interesting or may bring some smile on to that person's face sometimes we use pictures in a text for any important works like a school or office or whatever
