how do I bind one image src to another image src + jabascript code example

Example 1: jquery change image src

//change image src with jquery
$("#myImageID").attr("src","images/my_other_image.png");

//change image src plain javascript
document.getElementById('myImageID').src="images/my_other_image.png";

Example 2: can we give a url to img with jquery

$("#my_image").attr("src","second.jpg");
