This is how you do it:

var save = document.createElement('a');
save.href = $('#myImageID').attr('src');
save.target = '_blank';
save.download = 'photo.jpg'

var event = document.createEvent('Event');
event.initEvent('click', true, true);
save.dispatchEvent(event);
(window.URL || window.webkitURL).revokeObjectURL(save.href);

You need to trigger this code from a user gesture (e.g. click on a button).

Try this..

<script>
 var imagedata="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/..";
 document.getElementById('img').setAttribute( 'src',imagedata);
 document.getElementById('anchor').setAttribute( 'href',imagedata);
</script>

Working Example Here

Assign the image source to base64 string as follows-->

document.getElementById('img').setAttribute( 'src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==' );

Here you go,on right click on this image you can save it to your local drive easily. :)

If you want to download it onclick of button you have to use html5 download attribute as show here http://jsfiddle/3EjUg/5/
