Rebaking posts does not fix broken locally downloaded linked images

[vinothkannans (Vinoth Kannan)]

I agree, rebake should retry to download all broken images.

@sam

hard caching image is broken forever is a bit too strict here, at a minimum we should expire that information after N days.

I think it’s not needed after we implemented the both “retry on rebake” and “retry broken images N times in X hours” features. We can extend the X hours to 1, 10, 24, 72, 168.
