Its default value will be T (block), but people > who want to see remote images can customize it. I have no objection to this kind of knob in an already fiddly config space. In the other thread, i see the discussion of whether this should expose something fancier than a boolean, but given the number of possible rendering backends, i don't know how well we can support any of these options reliably. What should notmuch do when the customization variable is set to t (block remote images) but the html rendering backend doesn't support blocking remote images? It seems dangerous/disingenuous to offer the option to the user but not be able to enforce it in this case. Should having this set to t restrict the range of html renderers to only those that we can force to respect it? --dkg
