What is the src attribute of the img element. Typically, you can get a blob from that same source rather than from the img element itself. Typically you're using either a straight web URI, an in-app URI (ms-appx or ms-appdata), or a canvas, and in all three cases you have other ways of getting to the blob. – Kraig Brockschmidt - MSFT Dec 17 '13 at 03:53
