• Answer:

  If you are using jquery, it should be fiarly simple: Something like this: $('#btn').click(function(){ $('#myImage').attr('src','my_new_source.jpg'); }); You can also get this using regular javascript: <button id="btn" onclick="document.getElementById('myImage').src='newimage.jpeg'"> Click me </button>
