We had a flag on 2011 Moderator Election - Town Hall Chat Digest that the avatars weren't loading, and because it was meta, a user couldn't edit it.

with https would fix some proportion of these. For other image links, perhaps a script could get both the http and https version of any existing http image link, and if the results are the same then update link to https otherwise (maybe) get the http image and post it in i.sstatic.net Not sure if the rules would permit that last part.
