OK. Maybe a setting to determine how small is too small to render?
I'm not sure if Gaia apps are going to support something like
Firefox prefs... That said, if the HTML doesn't declare the image
size, we can't tell it's 1x1 without downloading it.

Well, that seems to make that plan impossible; leaving out size
attributes is a fairly trivial countermeasure. :(<br>
<br>
You won't be able to determine visibility as well if it is achieved
with transparency (or even a white pixel) without downloading the
image first. Maybe the "allow remote images" message could be done
in a less obtrusive way (e.g. a small floating "broken image" button
on top right, so there is no space penalty - this could expand into
"load remote images?" when tapped once)<br>

<blockquote type="cite">It might be interesting to run a testpilot
to figure out (a) how many external references and of what types
people receive in email, (b) how many of those declare their
sizes, and (c) the distribution of sizes (both declared and
undeclared) of those external objects.

counter measures would be fairly trivial, so I don't know whether
this is really worth the effort unless you plan on developing more
sophisticated methods - either way, welcome to the arms race :S<br>
