As I've noticed (and fixed in my userjs) serious slow down of HTTPS-CAA compared with HTTP-CAA (maybe due to bad Keep-Alive setting?), it would be nice if we could temporary force loading of HTTP images even on HTTPS-MB.

temporary fix: <img src="//coverartarchive.org/..."> → <img src="http://coverartarchive.org/...">

The noticed latency is around 4 or 5 seconds on HTTPS-CAA each time instead of less than 1 on HTTP-CAA.
