Execute a function within the context of every matched element. This means that every time the passed-in function is executed (which is once for every element matched) the 'this' keyword points to the specific DOM element. Additionally, the function, when executed, is passed a single argument representing the position of the element in the matched set (integer, zero-index). A function to execute Iterates over two images and sets their src property <img/><img/>

$("img").each(function(i){
  this.src = "test" + i + ".jpg";
});
