Per the EFF ruleset, https://www.eff.org/sites/all/themes/frontier/images/get-https-e-chrome.png should be rewritten to https://www.eff.org/sites/all/themes/frontier/images/got-https-e-chrome.png But in the chrome version of HTTPS Everywhere, it isn't. We also haven't implemented the "downgrade" rule attribute that allows rewrites to http, where those are required (although arguably because chrome blocks mixed content, this is much less useful than it is in Firefox).
