Save image to client browser using jQuery?

If you want to save an image using jQuery without click the button to get download the image. For that you need to trigger an action. 

In my case I am just I am getting the image path and see how I making the image to download on client browser. I got the data from the jQuery ajax call and returning the result.path. 

CODE:

  $.ajax({
            type: "POST",
            url: 'Home/IconUpload',
            contentType: false,
            processData: false,
            enctype: 'multipart/form-data',
            data: data,
            success: function(result) {
                varsrc = preview.src.split('/');
                vara = $("<a>")
      .attr("href",result.Path)
      .attr("download",src[src.length - 1])
      .appendTo("body");
               a[0].click();
                a.remove();              
            },
