And how? Using src attribute? that would have to be changed to accept 
both string and Blob object? What it would return on get operation? 
Libraries managing images (lightboxes) would have to consider, what does 
src mean? Or do you propose other attribute? What would then be in src? 
What if I change that blob? Should image change immediately as well? 
What if this was video playing?
