I tested this, but it didn't seem to work. I also still have similar issues with certain images, most notably images served from the media gallery? Also adding on top of the previous issue, now there are images that work, and images that don't work from the attachments folder.Not necessarily. There are a lot of variables as failed images are only re-requested so many times. You can explicitly refetch them via the control panel (clicking on a record for more info should force a refresh).
