The problem is that the following code might or might not work, depending on the behavior of the browser's GC: url = createObjectURL(blob); blob = null; setTimeout(function() { img.src = url; }, 0); If the timer executes before GC collects the blob, this works, because the URL is still valid. Otherwise, it fails, because--since the Blob no longer exists--the URL is no longer valid. -- Glenn Maynard
