alt is not a required attribute for img tag in html,
so if one doesn't want to use it, they can simply
leave it out...however, this only works if coded by
hand in a plain text editor. The problem, in my case,
arose from homesite, which automatically sticks and
empty alt="" attribute for img tags. I have since
removed all the alt="" tags, which removed the
recurring "true" in results.
I can see it as a bit cumbersome to have to do this
across all x/html files, especially on large sites.
I think a htdig.conf parameter for disabling alt tags
in indexing would be ideal.
