Monitor the form. Your monitoring tools should be telling you when bits of
your site break before users have a need to report the problem.

It's a test to find out if the agent that requested the page is human or some
bot of some sort. In order to progress past the form you have to enter
something into the box as a reply to some text in the form. If the question
and answer can be arbitary on a site by site, or better, hit by hit basis,
then it becomes infeasible to build a spambot to enter such sites.

I'd pregenrate them, give them an arbitary name and store a dictionary
mapping email addresses to the image for page building purposes.

I'm not sure what you mean by this. Can you explain?
(Not that I think image addreses are a good idea for all the reasons you
mentioned earlier. I'd prefer a slashdot style per user 'display address'
option. It can be obfuscated by default, but it allows the user to restore
there actual address, or render it unrecognizable depending on there personal
spam tolerance threshold.)
