I've just pushed Austin's shr related series to master, so this problem
should be fixed as of commit b74ed1c. One tradeoff that we should at
least remark in NEWS, if not actually fix, is that I think there is now
no way to view such images in notmuch.  I don't know offhand what other
html renderers will do.
