top-middle.png breaks https on Tor Weather.
When visiting https://weather.torproject.org/ TBB does not give it a padlock and Firefox shows an exclamation mark (I guess it would issue a message if I hadn't disabled that).
Upon looking into why that happens I saw that "top-middle.png" (http://weather.torproject.org/top-middle.png) gets served over http, although it is available over https.
