I would like to be able to control the ALT attribute in the IMG tag
of automatically-generated images. (I can already do this for
explicit images with \htmladdimg.) The following patch to
latex2html 2002 (1.63) extends the \htmlimage command to accept an
"alt" parameter, for example, \htmlimage{alt=some text}
