Need to pass full path to lonmeta::alttag().
The $token->[2]->{'something'} construction is apparently case sensitive,
so, for example, <img SRC="stuff.gif"> does not get recognized. Should this
module then not always call &Apache::lonxml::get_param instead of accessing
the token hash?
FIXED along the way: &image_replication was called BEFORE the full path
was figured out ...
