(In reply to comment #0) > Re-enable progressive image subsampling in WebCore This was turned off long ago (before iPhone OS 1.0 shipped) because enabling it caused hangs in WebCore. The blocking bug was fixed in ImageIO in iOS 8.0, so we're now able to re-enable subsampling of progressive JPEG images.
