We've got a ton of unused, obsolete images in zamboni. Let's do some cleaning.
Fixed in https://github.com/mozilla/zamboni/commit/0d4d7888e62061296acfcaa7e1b2e31c089b4717 QA: - Browse around the site making sure there are no missing images or broken styles.
Verified as fixed in FF45 (Win7) . We haven't found any regression from this bug. Closing bug.
