Use a data URI:

document.getElementById('e').src = 'data:image/png;base64,ton_of_crap';

In that Wikipedia article, there is code for PHP and Python that outputs base-64 encoded images. You can just shove that into the url() of a CSS file (or the src attribute of a <img /> tag) and it should work.

Have you tried (with jQuery):

$('#divID').css("background-image", "url(/myimage.png)");
