On a lark, I converted the few images referenced by my CSS file to data URLs. Seems to work just fine in the latest release of all major browsers.
I used the following simple script to do the conversions:
require 'net/http' ARGV.each do |arg| url = URI.parse(arg) Net::HTTP.start(url.host, url.port) do |http| res = http.get(url.path) break unless res.code == '200' data = 'data:' data << res['Content-Type'] data << ';base64,' data << [res.body].pack('m').chomp.gsub("\n",'') puts data end end
