I hacked the code for my own instance as follows. What this does is
causes the alt tags to be indexed, but they don't show up in the
excerpts.
>From htdig/HTML.cc in the do_tag method, for the "case 18:"
if (conf["alt"])
{
char *alttxt = transSGML(conf["alt"]);
if (doindex && in_title)
title << alttxt << " ";
// -- begin kaivo - don't want alt tags showing up.
// if (in_ref && description.length() <
max_description_length)
// description << alttxt << " ";
// if (doindex && !in_title && head.length() <
max_head_length)
// head << alttxt << " ";
// -- end kaivo
char *w = HtWordToken(alttxt);
while (w && doindex)
{
if (strlen(w) >= minimumWordLength)
retriever.got_word(w,
int((offset+(w-alttxt)) * 1000
/ totlength),
in_heading);
w = HtWordToken(0);
}
w = '\0';
}
Hope this helps
