How to Add class to all images inside div using jQuery?

Inside div I am dynamically loading inner text and it also contains img tags. After rendering dynamically I want to add class to all images present insdie that div.

I have tried this but its not working for me.

src of every img tag inside div is starting from data:image

function loadDiv() {

         // loading successfully div elements

          $("img[src*=data:image]").addClass("img-responsive");


     }
